Hallo Support team,

I ask for help,

I'm on my test server has created a site that works without problems. I moved to this web with akeeba tools to new hosting alive but there were a little problems. On the Homepage (cavemencooking.com) when I click on the any product, so this error occurs (see image).
After installing the new Web hosting with Akeeba tools, everything worked without problems. The problem occurred when I modified in any way, or simply just saved a module that displays products on the homepage (see image2).

Can you please advise me?

Unfortunately, I do not know what to do ((

Man many thanks,

Pavel
