Ah, I didn't think about the Advanced Forum being a plugin. Could be the reason for the error that Const is getting. Maybe this plugin doesn't work with his current (upgraded) moodle.
Sorry that we are getting off topic, but this seems to be the place where Const might visit. Also, it's about as far as I can go with helping him on his forum issue because I don't use the Advanced Forum plugin. (I will be quiet.)
Const, I am not trying to persuade you from dumping moodle, it is your choice. I am just pointing out that you can pay for moodle support just like you can pay for other LMS support. If your choice of LMS is influenced by cost, you should compare costs. Remember to compare features, especially those most important to you, also.
