If the forum breaks, can the forum be reinstalled using the original database? I removed a mod as it disappeared from the admin section yet was still installed. Now when I load the url its just a blank page and suspect there is something wrong with the subs file. Certainly a lesson learnt.

Its good to know that when something bad happens SMF is there to help, thank you.
