I found a fatal error in the moodle php log file:
PHP Fatal error: Call to undefined method resource_mrcuteput::print_toc() in moodle path\moodle\mod\resource\type\mrcuteput\resource.class.php on line 257
No member of staff reported a problem so I don't know what effect this had. I am assuming that someone was trying to add something to the repository and was unsuccessful (looking at the dates of files in the ims_repository folder).
Looking back through the logs I can see that the error has occurred before.
We are using moodle 1.9.8, windows, apache 2.2.14, php 5.2.9 and postgresql 8.2.
Can anyone suggest a reason / fix for this error?
