Hi,

this seems to be a problem inside the productcomments module or wtspecials module's tpl files, or php files. Did you modified something in it lately, since the error appeared?

Regards, Leo

[nycbicycleshop]

Hi

I didn't modified anything, I am adding the product from backend yesterday  and this happened, still backend works also all links works on the front end, only home page gives this error, any easy solution reinstall the modules or backup the temp and install again?

Thanks

[nycbicycleshop]

Is there any solution for this?

[tuk66]

Did you delete a product recently? Try to clear cache or disable Smarty Cache at all if it disappears.

waterthemes theme?? Have same crap with watherthemes theme

Edited April 27, 2016 by sennevb (see edit history)

[Prestachamps]

Hi,

after a small analysis the issue could come from module wtspecials, where in the tpl, the value for $_smarty_tpl->tpl_vars['product']->value is empty(possibly in the  file productcomments_reviews.tpl ), it should contain a product object.

You could try to disable the wtspecials module,to be sure that this module is the problem, or talk directly with the theme developer to fix this module.

Regards, Leo

Finally I disable the module 500 error gone, I uninstall the module and install again everything works perfect.

Thanks
