Hello everybody,

I'm using PrestaShop 1.7. Everthing working good till today, I tried as usual to visit my website on localhost : http://localhost/prestashop_1.7.1.2/ but infortunately recieved this error :

I installed a new free theme I activated this new one to see how it looks like... After a while I get back to my old theme (default classic theme) it still work but this evening nothing working only the back end .

Do you have any idea please?

Thank you.
