[solved]InvalidArgumentException when accesing BO

Recommended Posts

Hi guys,


My first post here, so hello to all. 

I`ve developed a store(on Prestashop 1.7.3) on localhost and I moved it to a live server. My process for moving from localhost to live server was: upload all shop from local to live server, create a dump from local db and imported it into the live server, and I`ve changed the "BASE URI" from the database, from "ps_shop_url". All thing work ok on the front office, but when I try to log in to backoffice, all I get is this  error:

Anyone has any ideea why is this happening? or how to fix it?

I`ve tried re-uploading the website, managed to log into BO -> SEO & URL page, to check if base uri is written ok, tried other pages, like administration, or catalog, or performance, they all gave a blank page. Went back to Seo&URL page, activated Friendly URL, and after that, couldn`t access BO anymore.

Check if the file debug.xml is on the folder  /vendor/symfony/symfony/src/Symfony/Bundle/FrameworkBundle/Resources/config/debug.xml

Perhaps it wasn't loaded.
