Changelog 2017-05-02[NEW] The current forum config file is now backed up before new changes are saved. Normally there would be no need for this step, though an incorrectly configured server or php.ini setting may cause havoc and corrupt the new config file creation process. A forum owner can now roll back to their backup config file, if the new one was corrupted upon its creation.
