Problem when updating CMSMS (FrontEndUsers renders problem)

[ArneDB]

Dear,

I'm trying to update my CMSMS from 1.10.3 to 1.11.3 so I can update to 1.12 and then to 2.x
I'm following this guide:
https://docs.cmsmadesimple.org/upgrading/old-versions

But I encoutered a problem at step 5, so I had to rename all my module folders, to continue.

After the update I renamed the folders again accordingly, but now i get the following error:
Fatal error: Cannot override final method CMSModule::can_cache_output() in /home/ryac/domains/ryac.be/public_html/modules/FrontEndUsers/FrontEndUsers.module.php on line 2097

Which in rendering a HTTP 500 error.

Anyone got an idea how to solve this issue?

I solved this by downloading the module from The Forge directly and uploading it via Binary via FileZilla
