I wanted to install this mod on my phpbb3 forum, the MOD install file asked to upload some files to specific locations, I did it but one of the file (index.php) was already present on the server. It even asked me if I want to replace it or not and I said yes Now nothing is opening on my forum, check yourself http://www.smsbucket.com/forum/ Is there any way to restore the forum?
As far as i've seen, you have replaced the "index.php" in root with the "index.php" from the mod's archive. You need to upload the original index.php back to your root folder. Extract it from the phpbb3-x-x.zip and then upload it. Then, pay attention because you shouldn't have copied index.php from the mod into the root folder, but rather into INSTALL . Hope it helps...
If you don't have the backup, you can restore it. If not try to upload an index.php from the original phpbb installation, it should be there in the original pack.
