[marc_gregori]

Hi,

I have a problem with any module instalation. The problem is that, when I install a module, later I can´t access to my backend. Magento shows me this error:

1 exception(s):
Exception #0 (LogicException): Could not create an acl object: Invalid Document 
Element 'resource': This element is not expected.
Line: 25

Hi @mark_gregori,

try once following commands one by one in sequence:

chmod -R 0777 var/ pub/ generated/
rm -rf var/cache/* pub/static/* generated/*
php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento setup:static-content:deploy
php bin/magento indexer:reindex
php bin/magento cache:flush
chmod -R 0777 var/ pub/ generated/

I hope it will help you!

Hi @marc_gregori 

Are you using any third-party premium theme in your store ? because the issue here is - resource id

Magento is looking for a resource id from the acl.xml but not able to get the same.

So you will require to debug/disable module one by one or may be a theme as well - and then check from where this resource id is not defined or not in proper naming conventions

That's way you will find the actual resolution for this problem

You can also try and run commands which mentioned in the above thread which might help you to resolve your issue.

Refer this link for more details - https://magento.stackexchange.com/questions/152792/could-not-create-an-acl-object-invalid-document

Hope it helps !
