TOPIC:

I have upgraded a XOT 3.10 installation to XOT 3.11 (clean install).
After that I applied the XOT 3.11 update.
Everything works fine except for the Export function. All of the options (Deployment, Scorm, Archive, Offline) stopped working.
I have tried to find something in the apache2 logs (error.log) but wasn't able to find anything.
It is an Apache 2.4 with PHP-FPM 8.1

I've now noticed that when I try to publish the project, I get an error. The Apache2 error.log has the message "client denied by server configuration: /myserverroot/xerte/editor/upload.php, referer: https://myserver/xerte/edithtml.php?template_id=103

I have created a new site configuration and the previous error "client denied by server configuration" no longer pops up in the error log. However, the export option still does not work.

The Apache error log mentions one error mentioning editorStyles.css can't be found. After a long search I found one error in ./editor/js/vendor/ckeditor/config.js where it says editorStyles.css instead of editorstyles.css. This has nothing to do with the export option so this still does not work.

I have now created a XAMPP installation with Xerte 3.11 and imported my Xerte archive in it. Here everything works. As on the Linux server everything worked fine with Xerte 3.10, I'm clueless why 3.11 works perfectly on the same server except for all the export functions.

Hi, is the php-zip extension enabled? That might be the issue.

Otherwise, try to enable $development mode (set $development to true around line 43 of config.php).

Try again, and see if you have an error in the apache log.

The zip-extension is enabled.
I'll try to enable the development mode and check whether there are errors in the apache log.

In the apache2 error log it says

There is no plugins folder in /var/www/xerte/modules/xerte/parent_templates/Nottingham/.
There is no such folder in the XAMPP installation but there it works.

Ah. Yes, I see. I fixed this. Replace modules/xerte/export.php with this one:

raw.githubusercontent.com/thexerteprojec...les/xerte/export.php

Thank you so much.
That solved it.
Apparenly your fix is needed on Linux systems but not for a XAMPP system on Windows.
I guess this file is not included yet in the updates as for the Linux and for the XAMPP on Windows I used the same xertetoolkits_3.11.zip and xertetoolkits_update_3.11.zip
Anyway, thank you very very much for helping me out on a Sunday!! And thanks for working on such an amazing application as Xerte.
