vBa ??? yeah if he have vBA installed then its the permissions from the vBa board,
however if he knows his admin panel link then he can just go directly to admin panel
without uploading any files or changes and change permission settings there if it is vBA ?
vBa does a great job locking people out, done it myself once..
Lol EDIT : yeah its sertainly vBa permissions teasing you..
direct link to your AdminCP then login and change
AdminCP -> vBa CMPS -> Quick permission editor.
