Tag Syntax

Enable {remove} Tags Select to enable the special {remove} plugin tags.
Remove Modules tag The word used for the Remove Module tag.
By default this is 'remove-modules'. So the full tag looks like:
{remove-modules module="My Module"}

Note:
If you change this, all existing tags will not work anymore.
Tag Characters The surrounding characters of the tag syntax.
Options: {...}, [...], {{...}}, [[...]], [:...:], [%...%]

Note: If you change this, all existing tags will not work anymore.

Assignments

This tab gives you the ability to disable any module assignment options for the module edit screen.

We advise you to switch off the assignments you don't plan to use, in order to keep the available assignment options in the module edit screens to only the ones you need, improving clarity and page load speed.

User Actions Log

Log User Actions Select to store User Actions. These actions will be visible in the User Actions Log module.
Events To Log Select the actions to include in the User Actions Log.

Permissions

Advanced Module Manager uses the core Module Manager permission rules.

The Joomla permission settings control access to the different actions for each user group. For more information on how these permissions work, see the Joomla docs: Access Control List Tutorial: Component Options & Permissions
