I've created my template and installed extensions everything worked fine. I work on localhost and then upload to my server and use searchreplacedb2.php to change the root url as usually.
But now, I can login and then access wp-admin in localhost, but on my server I can login (correctly and have the admin bar on top of the website pages), but I have a blank page a wp-admin/
I desactivated all security (extensions desactivated and files modifications removed in :function.php, wp-config.php, .htaccess updated on server) used on localhost, and uploaded the SQL database again, but no change, I still have a blank page.
define('WP_DEBUG', true); → wp-admin still blank page
Where should I search for a solution ? Thanks for help !
