We're getting this error which was previously reported in another thread:
Error: could not find records
http://moodle.org/mod/forum/discuss.php?d=77242
It's also logged in Moodle Tracker:
http://tracker.moodle.org/browse/MDL-10733
In our case, it has nothing to do with an upgrade or continuing a lesson that was previously started. Students get the error whenever we add a link to a specific page in the lesson. They can't go straight to specific pages unless they've already viewed the main lesson page.
Is there a workaround, other than the code changes described in the previous thread? Could we use conditional statements to apply the changes to specific courses instead of applying it globally?
