davcal is unmaintained, no further fixes will be implemented from my side.

Finally, this should be fixed in rDAVCALe4bc2b1c0d4a53495d69bc0e916c5e70b3941ea2. Feel free to reopen if it doesn't work as intended.

OK. Thank you for your analysis. I will try it. Many thanks.

Thanks - DokuWiki thinks the request is a CSRF attack. The reason is that some requests are performed to your uppercase URL and some to your lowercase URL. I suppose that IIS invokes separate PHP instances for the different URLs and thus the security tokens do not match.

Then we need to go the more complicated route and I have to ask for more details:

Unfortunately, that's not possible. We are using DokuWiki in our Intranet. Access from outside isn't possible.

OK, then my theory is probably wrong :(

Sorry, I've forgotten to write that we are using IIS. You are right, DokuWiki and dokuwiki are separate folders – on UNIX systems. But using IIS on Windows Server, both names refer to the same directory. Therefore, we are able to use both styles. It works with all pages except pages using davcal.

Short answer: dokuwiki and DokuWiki are - usually - two separate folders and you should *never* mix them.

Thanks for the patch, I'll review and apply it as soon as possible (there is another patch pending that arrived via E-Mail that needs some work as well).

OK - it sounds feasible and would need to be done entirely in JavaScript. Unfortunately, at the moment, I don't really have the time to work on this.
If you want to give it a try, I'd be happy to give you some guidance. If not, it's going to take a while, I'm afraid.

Yes, this is exactly what I meant.

Could you be a bit more specific with what you mean? What exactly should the setting prevent/disable/disallow?

OK, I can see the problem with the datepicker in bureaucracy now. This seems to be a "feature" of the underlying fullcalendar.js library, though. I'll need to investigate that a bit further.

Thanks for your comment, much appreciated! It should be fixed now, would you mind having a look again?

Yes, I had the problem with 2017-02-19e and the current hg checkout of your plugin.

Thanks for the report. I cannot reproduce this on 2017-02-29e, the interface language of davcal follows DokuWiki's language for de, en, fr and nl. There is indeed a bug regarding datetimepicker which is always English (easy fix).

Of course this breaks the localization of the calendar view itself.

Perfect now it works again :) I thought i made a mistake.

No problem, I introduced a nice regression - I should definitely do more regression testing before pushing updates!
Anyway, please try the latest update published just now. The problem was/is the "C:" in <C:calendar-data> which confused the XML parser - I fixed it in 447fc5d456c1.

I'm sorry to hesitate you again.
Today i was working on the dokuwiki and recognised, that the plugin still dont work.
After that i saw the update for webdav
I updated the webdav plugin but nothing changed.

OK, I'm glad you got it working. I'm pushing an update anyway just now, since you discovered a bug with this broken XML tag.

It works now!
I updated davical from version 1.1.3 to 1.1.5 about backport package made a resync and now I see the data.
So I guess there where changes made for debian stretch.

Thanks for the quick response. Obvisily nothing changed i deleted brwoser cache etc.
Do you need access to my system?

OK, could you try the following:
In function clean_response (helper.php:1364), add as first line of the function:

$response = preg_replace('/xmlns[^=]*="[^"]*"/i', '', $response);

This might fix it, if not, we need to find another solution.

Thanks, that is the relevant part. The function clean_response messes the response up when davical is used (I only test against Sabre/DAV resp. NextCloud). It might take a bit until I come up with a solution, but I'll make that a high priority task.

This is helpful, although webdavclient doesn't seem to log the raw response. There seems to be an empty tag <''> which is closed by </multistatus> and that probably confuses simplexml_load_string().
Could you add the following line in helper.php on line 1126 (right before $response = $this->clean_response(...))

Hm, seems to be related to davical. Unfortunately, I can't test this since I do not have a davical installation.
Please enable debug logging and force a sync. Then, you should be able to see some XML output in the debug log - be aware that your calendar data is included here!

Actual i found this at the apache error.log

What exactly are you trying to achieve? You want to synchronise your DokuWiki calendar to davical, right?
Did you configure WebDAV connections in the Admin section? If so, were you able to display the available calendars?

I don't really understand your question. What I've understood is that a user should have read/write access to a calendar when he's logged in to DokuWiki. This is the exact behaviour. Put simply:

Sure :)

Well, we're generating secret material, so I guess it's cryptography ;)

That's right, as davcal is tested and being developed with this version of sabredav (which is also patched to support PHP7). I'm not going to update for no good reason, feel free to provide a patch, though.

Thanks for the documentation, please feel free to add it to the Wiki at www.dokuwiki.org/plugin:davcal

Thanks for your suggestion, I did not know that random_compat exists.
However, I still consider the implementation with uniqid as appropriate, because:

yes it works perfectly now. thanks !

Could you check whether the latest update fixes your problem? The downside is a scrollbar that appears, at least for me.

Oh well: this doesn't happen in Chromium, only in Firefox!

Finally, I'm able to reproduce your problem, at least partially: It happens to me only in month view and only in the lower three rows of the calendar. It does not happen with an older version of davcal, so it might be either a regression or a bug in fullcalendar (which was updated due to a newer jQuery version in DokuWiki).

Is there anything that I should change ? every plugins look up-to-date.

Hi,
I have only one calendar on the page.
I call it the easiest way possible: {{davcal>}}

OK, let's debug that a bit further:

does someone have any idea about our problem ?

here is what is on the server log:
[Tue May 16 14:13:15 2017] [error] [client ip adresse] client denied by server configuration: /usr/share/dokuwiki/data/security.png, referer: https://ourwebsite.fr/doku.php?id=clic:calendrierseeg&do=admin

Hi,
in the developer tools, in console, nothing happens when I click on a day.
I have this :
"JQMIGRATE: Migrate is installed, version 3.0.0 jquery.php:20:440
Use of getPreventDefault() is deprecated. Use defaultPrevented instead."
it appears at the begining.
I have nothing added to the console when I click on a day or when I modify an events.
I'll look on the webserver log.

Hm, that sounds indeed a bit weird. Are there any error message in either the webserver log or the browser log? Could you open Developer Tools in Firefox or Chrome (F12 for both of them), click on a day and see if there is an error logged in the console?
Sometimes, also the installation of another, presumably unrelated, plugin trigger an error?

Seems that latest jQuery 3 code in DokuWiki broke fullcalendar, on which davcal is based. Probably, an update of fullCalendar can fix this.

Yeah, mine looks similar to yours. You can try to style the calendar output by modifying fullcalendar-2.4.0/fullcalendar.print.less (it's a standard CSS stylesheet).

I have uploaded calendar printed from browser (dokuwiki.pdf), and for reference a very nicely formatted calender printed from osmo organizer (osmo.pdf). Google calender has more or less also similarly nice export / print to pdf.

Yes, please upload a screenshot of the differences. I just tried printing (Firefox 49.0.1) and IMHO it looks very nice! Day/Week view are more condensed in print, but that could be by design (fullcalendar's unmodified print stylesheet is applied).

Hi,
printing is indeed currently possible from the browser, but the output is quite ugly. I had in mind adding nicely formatted calendar output/export functionality. If it is not exactly clear what I mean, I can attach, or send you two sample outputs (one current, and one desired for comparison)

Thanks for your comment.

A basic editor for events created within DokuWiki doesn't seem too difficult. However, making it compatible with events created and/or modified by other clients is the hard job.

If you read through the documentation, you will find the option "timezone" which should solve your problem.

This would be a nice Admin Plugin...

OK, I found the problem: It's the PHP7 update and an incompatibility with the version of Sabre/DAV I'm using for davcal. See the problem for ownCloud, I applied their patch: https://github.com/owncloudarchive/calendar/issues/1002

I'm currently testing a few things, it seems that OutlookCalDavSynchronizer requests only events within a certain time span. davcal does not report any events back, so it looks like a problem somewhere within davcal.

Your link is correct.

Did you use this one: https://sourceforge.net/projects/outlookcaldavsynchronizer/?
