In recent days, an error occurred up on many Prestashop websites making access to the back office login page impossible.
PHP Fatal error: Class 'AdminLoginController' not found in /.../.../public_html/classes/controller/Controller.php on line 134
The main cause of this error simply is that the contents of a PHP file have been fully emptied.
Solution is very simple. You need to restore an original file which is located in /controllers/admin.
Original file you can find right here.
Additional information
You can revoke the writable rights of the file to prevent this problem in the future.
Hi, I have run into this problem and tried this but it still doesn’t work… any ideas or help would be great. Using prestashop 1.6.1.4
Identical error? Did you try to clear cache via admin panel and/or delete class_index.php in /cache folder?
Excelente aporte! muy buena solución! Gracias
