Hi Alice - as I said before, 52 IS the default, and if you have been able to use 82 before then somebody has changed it in the code. You can't alter it within Moodle but if you have access to your
server or your Moodle admin can do it then I will try to find the way you can increase the topics to more than 52. I can only assume it was done in your earlier version and not carried through to the upgrade.
edit Ok here (courtesy of Larry Elchuck in earlier post) Note it is v 1.9.5 so the numbering might be a bit different now.
The line to be changed is in course/edit_form.php and it is line 117 in the latest version (v 1.37.2.17) of the file for Moodle 1.9.5
Change 52 in
for ($i=1; $i<=52; $i++) {to whatever you like.
Now that I have found it, could I
please beg you to think again about sooooo many topic sections? You must have the longest page in Moodle - and what about your students who need to scroll all the way down to 82?
