[Matteo]

Hello to all,

For non italian:

It's says that some server's error occured while loading tables but we can't find nothing on log files.

 

Can u pls help me?

Thanks in advance,

Turn on debug mode in  config/defines.inc.php, then then on the product page (or before clicking on the product) hit f12 on chrome, navigate to the Network tab, then access the product page. One of the XHR calls will be red, likely on of the tabs. Try disabling those TM modules to start with and see if the error goes away.

We've find that the problem is related to a cache error cause by smarty cache (ps interna) that sometimes can't generate tpl files.

U know why?
