It was working previously? I don't believe there were changes to the security code, but did you check your config.php file? Are the GD libraries installed on the server?
You can try running the new Analyzer script to do a more comprehensive test for security codes
Im really new to PHP so I don't really know where to check, it was working before yes. I just replaced the files and edited the config.php file and it stopped working. Is there a part of the config.php file that is for security codes?
make sure that your config.php doesn't have empty lines at the end... (after the "?>") - this is what may cause your errors with the image needed for login
Did you make sure you uploaded the new/changed config.php file to your server? I forgot to do that once and could not understand why the changes I had made were not taking effect.
Delete all of your cache and cookies, you may be the only one NOT seeing the change you have initiated.
Sounds dumb, but... well... ya know!
Or am I the only one who does these silly things?
I've refreshed and refreshed and refreshed unable to see a change, then clearned my cache and all of a sudden, there's my change.
I think he must verify if there are empty lines after the "?>" at the end of the config.php file.
I had the same problem many times until erased those empty lines
