I upgraded this site last week and had no occasion to look at the products. But when attempting to do so today, I get the above error message.

Thanks for your help!

Hi,

Thanks for the feedback. We've added a patch for that issue which happens only with Joomla 1.5 and 2.5. Download again the install package on our website and install it on yours and that will fix the problem.

Thank you for your help! The patch resolved the problem. I'm grateful!

Hi Nicolas,
I have the same problem of gmarsh (Joomla! 2.5 and Hikashop 3.1.1) but when I try to install the new package it return a 500 error. How can I solve the problem?

The zip package works great and fix the problem. Thanks a lot!
