    We use this plugin on our Moodle 2.7, it's not mentioned on this page that this plugin is valid for 2.9 and 3.0. Can you plse confirm ? and ideally update this page to mark this plugin as valid after 2.8 ?

    Hi Timo. Many thanks for providing this plugin to the community; its functionality is really appreciated by our staff and students, and we’re really grateful to you for your efforts to maintain and update it.

    On that note, please could I quickly query whether you have any plans to update the plugin to be fully compatible with Moodle v3.1, and its new Global Search feature in particular? To clarify: while we’ve tested the Etherpad Lite plugin under v3.1 and all of the core functionality seems to work fine, we’ve found that instances of the activity are not searchable via v3.1’s Global Search feature. Please see the following screenshot for details, which lists all of the available areas that can searched under v3.1 (note that these settings are available via: Site Administration -> Plugins -> Search -> Manage Global Search):

    Note also that the above screenshot was taken on a v3.1 system where the Etherpad Lite plugin is installed and available. However, as you can see, the Etherpad Lite activity is not listed as being available to be searched. Obviously, this is likely to be a significant problem/cause of confusion for users who might want to search for specific instances of the Etherpad Lite activity across Moodle.

    I’m not a developer, but my understanding is that mod plugins can be made searchable relatively easily via the addition of a new search class within the plugin’s codebase (located at ../classes/search/activity.php). Please see the following for further details:

    We really hope this search capability can be added to Etherpad Lite as I’m sure it would be a huge benefit to our users (as well as those of other v3.1 systems) and, again, many thanks for all your efforts to develop this plugin and share it with the community.

    Best wishes,

    Hi, i installed etherpad.lite ob an ubuntu machine and its working (Plugins: draw, fileupload). Your Ehterpad plugin in moodle 3.11+ is installed without errors. I put my API key in the plugin preferences and take the right url with a virtual host to localhost/pad/. The etherpad is loading but i get the error "Sie haben keine Berechtigung, um auf dieses Pad zuzugreifen", it is a permisson denied error. I am admin and trainer of the course!? so why i get this error message?

    Hi, Since the firefox and chrome latest releases, we are facing a lot of issues with our etherpad in Moodle, "No access to pad"...
    We use etherpad for our moodle + redmine, both are running with the same server, with reverse-proxy,
    The only differences are regarding access configuration
    + slightly version difference : moodle instance : 1.5.7 sur redmine instance : 1.6.0
    I wonder if others are facing the same issues ??
  • Hi Emilie, even if we have also heared of such things, we have not been able to reproduce them in our environment by now and to debug them. Hopefully we will find the time to release an up to date version which comes without such issues.

    Hello, I just updated my server from Windows 2012r to Windows 2016. I start getting the following error when I try to open old course's EtherPadLite or create a new one: "Exception - Empty or No Response from the server" on Moodle 3.1. It worked fine on Windows 2012r. Also, when I run EtherPadLite directly, without Moodle, it works fine. Any ideas? Thanks, Eugene
    PS I also had problems with accessing Question bank on Moodle after Windows update, but I solve it by lowering the version of PHP from 7.0.9 to 5.6.30 (64-bit). This did not help with EtherPadLite....

    Update on the "Exception - Empty or No Response from the server" error. With the help of our IT colleagues, I found problems with my DNS settings on my network adapter card. Also, IPv6 causes problems as well and has to be disabled on my network adapter. Etherpad works. The problem is solved.
  • Hello Eugene, we're glad to hear that the problem wasn't a persistent and generic ep problem and at least is solved smile

    Hello dear community,

    We upgraded our Moodle to 3.5 and hoped that Etherpad 2.7 would still work. But we get the following error when creating an activity:
    Empty or no response from the server

    The apache log:

    Database transaction aborted automatically in /srv/www/htdocs/moodle/course/modedit.php, referer: ...

    Default exception handler: Error: Empty or No Response from the server Debug: \ nError code: generalexceptionmessage \ n * line 107 of /mod/etherpadlite/etherpad-lite-client.php: UnexpectedValueException thrown \ n * line 60 of / mod / etherpadlite / etherpad-lite-client.php: call to EtherpadLiteClient-> call () \ n * line 148 of /mod/etherpadlite/etherpad-lite-client.php: call to EtherpadLiteClient-> post () \ n * line 62 of /mod/etherpadlite/lib.php: call to EtherpadLiteClient-> createGroup () \ n * line 124 of /course/modlib.php: call to etherpadlite_add_instance () \ n * line 154 of /course/modedit.php: call to add_moduleinfo () \ n, referer: ...

    If we call Etherpad directly and not via the Moodle plug-in, it works. Our assumption that Etherpad-lite 2.7 for 3.5 is not compatible seems to be confirmed.

    Did anyone get Etherpad Lite running at 3.5?
    Are there plans to further develop Etherpad Lite for Moodle 3.5?

    Excuse me if my english is bad. The Google translator helped.

    Best regards,

    My students and I started getting errors on EtherPad after I updated to Moodle 3.8.3+ (Build: 20200527), the Etherpad plugin for Moodle version 2019013100, and Etherpad Lite server to 1.8.5. We cannot open an etherpad. The problem is unpredictable but it appears when 20-30 users access an etherpad embedded in Moodle at the same time. Here is a typical error message:

    ErrorId: 4wNmhAZ2hYo9zBrq1xHb
    URL: https://myaddress:9001/p/g.NfRQhXclxTNNzHYW$DiaMoodle
    UserAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:80.0) Gecko/20100101 Firefox/80.0
    TypeError: $sidedivinner is undefined in https://myaddress:9001/static/js/require-kernel.js?v=c4855223 line 1 > Function at line 5

    We do not have a problem when we use Etherpad directly without Moodle.

    I never had this problem before with previous versions of Moodle, plugin, or Etherpad Lite Server. Any ideas what cases it and how I can resolve it, please?

    PS I set minify to false and AgeMax to 0 in settings.json of Etherpad Lite Server. It seems to help a bit but not completely...

    I love Etherpad. How do I get the API key or host?
  • Thu, Oct 20, 2022, 9:55 PM
    Untill Version 2021073000 the Etherpad Plugin worked for us. In newer Versions we got the Error: Could not get api version
    Now I debugged a little bit and found out, that in the file
    etherpadlite\classes\client.php in the function get_version() the
    $url = $this->baseurl;
    ends with
    and not with
    what leads to an Etherpad instead of the JSON. After adding the missing slash with the following code it works for us:

    if(!(substr_compare($url, "/", -1) === 0)){

  • Mon, Dec 19, 2022, 2:53 PM
    I was able to get rid of the error message "Could not get api version". so now I can create a pad in Moodle, however I cannot access it within Moodle.

    The error message I get is " has refused the connection."

    Best regards
