My Bad for not specifying this earlier, I am using version 173 of FEC. I haven't looked at 151 but it may not be compatible for 1.39.

NickP: If you turn off the FEC mod, then it is not your problem. Did you edit a core file to add it to your store? If so, put a copy of the original file that was edited back in and see if that clears the problem.

Remember EVERYONE, if you have a problem on a page, it HELPS A LOT to leave a link to your sight if you can and tell us what version of zen-cart and the mod you are using. This way it can be looked at and it might make the fix a lot easier to find.

Remember, Always BACKUP your files and DB Before add any modification!
