math tags / custom bbcode error

[pjkcards]

I notice on my forum when the math tags are being used, the error described here comes up.

I looked if there was a custom BB code for that tag, but didn't see it. What is the best way to troubleshoot this? Thanks in advance.

That must be from a mod - maybe try looking in your product manager and seeing if you can spot any likely suspects.

The error could be a file permission problem. The function touch() sets the modification time on a file, so if it's failing it's likely that the script doesn't have the right permission. But there's no way to know what file it's trying to touch() without seeing the code.
