When I try to create a new topic containing the text string “math” in either the title or the topic text, I get a “500 error” pop-up. Doesn’t seem to matter which category. We do have a tag “math,” but the sample post triggering the error is not tagged. If someone creates a post with an alternate spelling like “m ath,” the user is able to go back and edit “m ath” to “math” successfully. The topic create seems to be the point of failure.
Any help would be greatly appreciated.

The error log reports:
