Hello,
I have 3 sites running Zen Cart (each one using the same version of Zen Cart (currently 1.3.9f) and the same templates.
Two of them work perfectly with no issues, but the 3rd one seems to have developed a strange bug.
Initially when i try to go to edit a product i get the error message "Mozilla < 1.3 Beta is not supported!" if i click ok, i am then taken into the product listing page - but the contents of the product listing is all deleted.
I have changed the text editor to text rather than HTML which removed this error message, but the contents of the product listing is still being deleted each time i try to edit it.
I have no idea why this is happening, why its started or where to even start with resolving this issue, but obviously i cant carry on with it being like that!
Can any one suggest anything i can look at.
I have tried this on both Google Chrome and also I.E and it is happening on both browsers.
