Access denied. blank page on BO

[Kowjirow]

Hello everyone.

I'm asking help to the community! I have a problem with my back office. I have a blank page with access denied when I try to connect to it.

https://www.impactshop.fr/admin*****/index.php?controller=AdminDashboard&token=*******

Do you have any idea what could create this? my host asked me if I had configured a connection via a specific IP, which could have created the error but I did not do anything.

in debug mode, i have nothing (blank page) but when it's false now, i have e message:

Fatal error: Uncaught Error: Call to a member function get() on null in /home/www/prestashop/prestashop/classes/Link.php:701 Stack trace: #0 /home/www/prestashop/prestashop/classes/controller/AdminController.php(1999): LinkCore->getAdminLink('AdminProducts') #1 /home/www/prestashop/prestashop/classes/controller/AdminController.php(2000): AdminControllerCore->getTabs('122', 2) #2 /home/www/prestashop/prestashop/classes/controller/AdminController.php(2000): AdminControllerCore->getTabs('115', 1) #3 /home/www/prestashop/prestashop/classes/controller/AdminController.php(1868): AdminControllerCore->getTabs() #4 /home/www/prestashop/prestashop/classes/controller/Controller.php(251): AdminControllerCore->initHeader() #5 /home/www/prestashop/prestashop/classes/Dispatcher.php(428): ControllerCore->run() #6 /home/www/prestashop/prestashop/admin641rjcdt0/index.php(54): DispatcherCore->dispatch() #7 {main} thrown in /home/www/prestashop/prestashop/classes/Link.php on line 701

I don't know how to do that without the dashboard. What file do I need to edit?

Could you execute the following query and post the results?

SELECT * FROM `ps_tab` WHERE `id_tab` = '115' OR `id_tab` = '122'
