Fix 2 bugs in prestashop :: Bug 1: If I turn friendly URL on in the back-office, I can't see my website (front) anymore in the browser I become blank pages. :: Bug 2: We created in a development environment a new webshop: [login to view URL] So the development webshop is OK now and we created a new hosting account on the same server: [login to view URL] and copied all the files of the development environment on the the def account ([login to view URL]). There is no problem to go in the admin part of the new webshop [login to view URL] But if we type in the browser [login to view URL] it goes automaticaly to [login to view URL] (our development environment) If we change in the admin part ([login to view URL]) under preferences >> SEO &URLs the 'shop domain name' in '[login to view URL]' we become a blank page. In the ftp account of the new hosting account [login to view URL] we can see that all the files are correct uploaded (even the [login to view URL] file). Maybe a .htaccess problem? Note: to solve temporary the problem we created a [login to view URL] page with a javascript for a URL redirect
