Won't let me run upgrade.php

[jmmc]

Hey guys, this might be silly and it's first time happening for me and i dont know what to do.
So Im upgrading my 1.4.x to the latest version and I replaced all the files correctly etc but when I try to run upgrade.php I get the 'board is offline' message and it seems like somehow the gallery logged me off and now when I try to log in the "Fatal error :" appears.
What should I do to fix it? :/

Thanks in advance!

In your database, open the config table, find the value "offline" and change it to "0".
