Weird forum errors?

[Sushidragon]

I tried to add a couple of mods to the forum and failed a little.. XD; I reuploaded all of my backups, so in theory everything should be working fine now. If you do encounter any weird errors, please let me know and I`ll try to figure out what`s going on.

I go this one when trying to preview a new signature:

General Error
SQL ERROR [ mysqli ]

MySQL server has gone away [2006]

An SQL error occurred while fetching this page. Please contact the Board Administrator if this problem persists.

No idea what it means though! >_>;
