You are using a very old version of Zen Cart, which is no longer supported.

And the symptoms you are reporting are symptomatic of a bug that existed in that version.

The BEST solution to your problem is to upgrade your site to the latest version of Zen Cart.

Ok, many thanks for you. Need to check how difficult to uppgrade, I am rather amateur with this program.:huh:
