Upgrade from 1.3

[Norwegian_Rat]

Hi.

 

I've run into a little issue when I was about to upgrade a store from 1.3 to stable/bleeding edge. When I hit Modules page I get the 500 error page. When decrypting the error it gives me this:

Decoded exception

method_exists(): Argument #1 ($object_or_class) must be of type object|string, bool given

in file classes/controller/AdminController.php at line 3460

line 3460:3460: if (method_exists(Module::getInstanceByName($module->name), 'reset')) {

 

We're on PHP 8.0 atm. 

 

Is there an easy fix for this, or did we screw up by not upgrading when we was on php 7 ?

 

Regards
