Problem open page products

[FerreireX]

Hi,

When I open a product page shows me this error.

Whoops, looks like something went wrong.
(1/1) ContextErrorException

What made this error happen?

Well, the error said: there is a variable "category" on the "product.tpl" file that is not defined. You should find it and probably use some condition like "{if isset($category)}" before using it. Anyway this is just a notice, you will not see it anymore after you disable debug mode.

Thanks @Rolige

When I turn off the debug mode the admin page shows just as a white page, don't know why this happens.
