Uninstalling the software
Simply uninstall the module. This will disable the extension. That’s it. You can now safely remove all the Member Utilities files. Please refer to the installation instructions for a list of the related files.
Don’t forget that if you have converted the exp_sites.site_system_preferences field then you can have that field reverted if you wish. The pre-installation configuration instructions have more information about this.
If you have other software installed that might have converted this field or you did it manually then please make sure that you have considered the consequences of reverting it.
