Ok.
The thing is that the plugin worked great on this site before we migrated it to the current domain. We still use the same webhost as before, just migrated the site from one account to another.
Is there any setting saved in a file that doesnt reset when reinstalling the plugin thats might still point to the old location?
I just cant get my head around why it was working at first, but not after migration when we still use the same hosting service.
Cheers !
