Unable to create categories

Thank-you!! Did some searching online and it appears that line is added by some app called Fantapper, which is something or host has installed on all websites :/ Going to talk with them about it now.

You should look at the function rebuild_tree in functions.inc where the problem is reading categories one by one then updating in a loop

Unfortunately, with the current design, I haven't found a better solution for this issue, as the whole category tree needs to be rebuilt on certain actions. Probably we could decrease the amount of SELECT queries, but I currently don't know how to decrease the amount of UPDATE queries.
