Changing company settings results in 404

Hi everyone,



I'm trying to change company settings on one client's site but as soon as I hit Save, it gives me a 404. This has happened before with a different client and at the time I ended up making the changes through phpmyadmin, but I need to know what the cause is.



Can anyone help?



Thanks

Sounds like a possible permissions error on the relevent file.

Thanks for the reply. Could you shed some more light on this? Which file should I look into? You're obviously talking about CHMOD right?



Cheers
