I've searched via google and manually through the forum but can not find any solutions to this problem. We seem to be having random students (and some teachers) saying they can not post to forums over a certain number of characters. They are getting a range of errors depending on their browser type:
There are two ways it seems to be happening:
1) When students copy/paste text into the forum
2) When manually typing and it seems to "exceed" a limit.
I have dropped the re-edit time down to 5mins, but as I understand the documentation this does not affect the original post composition time.
I've increased the max_execution_time from 30 to 300 seconds and the max_input_time from 300 to 600 seconds. I don't think this should affect what is going on here however.
As it stands students are having to post comments in two separate posts now which is less than ideal.
Any suggestions greatly appreciated.
