Admin back office 500 error blank page after moved hosting PS1.7.6.4

[rayleic]

Hello friend,

My PS version is 1.7.6.4. The store works well in the past and after I moved hosting recently, only the front page works well, can't login admin page as it is 500 error blank page. I have tried many ways such as delete var/cache folder, check permissions, revise the php version to 7.3 or 7.2, all not work.

Anyone please help, thank you so much!

I set the debug mode and get this at my admin page:

(1/1) UndefinedMethodException

Attempted to call an undefined method named "jschecks" of class "AdminLoginController".

in Controller.php line 634

at ControllerCore->smartyOutputContent(array('/home/czybzzlr/public_html/ abc.com/admin818moda/themes/default/template/controllers/login/layout.tpl'))in AdminController.php line 1885

at ControllerCore->run()in Dispatcher.php line 515

at DispatcherCore->dispatch()in index.php line 97

In the error_log file of admin folder in cPanel, the message as below:

Can anyone help? I also have woocommerce and opencart, never got this kind of issue. And it seems it's very difficult to upgrade to newer version than wordpress.
