Remote file is too large (Error when saving signature)

[vBNinja]

Hello,

I recently moved my forum to a new server, we are now also running on litespeed

Many users have been having issues with changing their signatures. When they click save, it gives themna vbulletin message saying "Remote file is too large".

They have tried small and big images, for some odd reason they said that a 500 x 300 px image works and a 400 x 250 image doesnt

Does anyone know what may be causing this? It was working fine before migrating servers.

Thanks in advance
