Translations:J5.x:How to Delete Access Levels with Table References/2/en
From Joomla! Documentation
The feature introduced in Joomla 5.2 simplifies the deletion of access levels by providing clear information about where an access level is being used. Previously, if an access level was in use, Joomla would prevent its deletion but without specifying where it was being applied. This update adds a detailed error message that includes a list of the tables referencing the access level, helping users to locate the content linked to it.
