or if you are needing to login right now and you don't want to remove the offending plugin yet you could just try and change like i just did for giggles on recreating your issue on 1.8.25 using latest plugin file on mods site:
viewgroups.php line # 36
if(THIS_SCRIPT == 'index.php')
to:
if('THIS_SCRIPT' == 'index.php')
and you will be able to login again, right?!
this is the slightly edited plugin file I was using on...,
MyBB Version
1.8.25
PHP Version
7.4.14
SQL Engine
MySQLi 8.0.22
I only say slightly edited because there was some issues on install for me and not wanting to look much into a plugin I am not familiar with I simply edited to make my install happen as quickly as possible as was the objective simply to see your issue:
