I suppose this was already fixed in cvs, but there are still some problems with cvs update, right Nicolas?
There may be, but I have no idea how this can be solved.
This continues to be an issue in 1.9.3+ (Build: 20090106). With debugging set at MINIMAL, a blank page appears, but when set to ALL the following message appears:
Warning: require_once(HTML/AJAX/JSON.php) [function.require-once]: failed to open stream: No such file or directory in /var/www/moodle/group/index.php on line 14 Fatal error: require_once() [function.require]: Failed opening required 'HTML/AJAX/JSON.php' (include_path='/var/www/moodle/lib/pear:/var/www/moodle/lib/pear:.:/usr/share/php:/usr/share/pear') in /var/www/moodle/group/index.php on line 14 This server has never had anything other version than 1.9 on it. Clinton (and whoever still has problems with this), which version did you update FROM? This may be important in determining the cause of this annoyingly unreproducible bug.
At least in one user's case the problem was that the AJAX directory doesn't even exist. This user installed Moodle via CVS and had the latest version.
The server was set up with CVS on Ubuntu last summer and has been updated via CVS about once a month since. Unfortunately I did not keep track of every version at every update.
I need to mention one other interesting factor since my last post: I had been using "cvs -q update" However, the last update I used "cvs -dP update" This seems to have resolved the blank page that previously appeared when trying to set up groups. I am not sure why the "P" option (Pruning empty directories) fixed the situation. A thank you to Dakato Duff for their advice in the GROUPS forum.
I didn't have an AJAX directory. I tried the suggestion from Duff to copy their AJAX directory. I did, but then when I updated using CVS, CVS wouldn't recognize the directory. I would always update via CVS using like this: cvs -q update I tried what Clinton Branscombe did but just got an error from CVS. I am running moodle on a Debian LAMP server. I searched around and found this reference for updating with CVS: http://www.csse.uwa.edu.au/~gian/cvsintro.html#update I tired this command with cvs cvs update -dP This fixed the groups problem. I now also have an AJAX.php file and AJAX directory in my var/www/moodle/lib/pear/HTML directory. -dP is correct. See http://docs.moodle.org/en/CVS_for_Administrators
 .
I guess that means that this issue can be closed now? most probably upgrade issue only, the code looks ok

Wrong include in group/index.php

require_once($CFG->libdir.'/json/JSON.php');
Also, on lines 83 and 91 have "json_encode"... I don't see that function in the include (or anywhere in Moodle actually). Is it supposed to be just "encode" (which does exist under the include listed above)?
Thanks
