I am trying to remove extensions that were previously installed, but the only way I have been able to do it is editing the module files under app/etc/modules and changing
<active>true</active>
to
<active>false</active>
Is there a way to completely remove the extension as if I had never installed in the first place?
When I view my Magento Connect Manager, none of my extensions appear under the existing extensions list.
Thank you!
You are able to remove all the models via the Mage Connect interface:
System > Magento Connect > Magento Connect Manager
Set all the modules to uninstall and then they are getting removed.
Actually, there's no foolproof way to fully remove extension once it's installed to the system.
While it's easy to remove bootstrap file from app/etc/modules and main code from app/code/{codePool}, there's no way to determine what other payload this extension had. By investigating code, configuration and resource files, it's possible to locate majority of additional tables, translation files, templates, layouts, database objects, stylesheet, JS-s and images, but even after major detective work there's good chance the some leftovers remain.
Also, it's almost impossible to remove payment methods, as Magento store references to them to orders and invoices and so on. Once you remove them, any attempt to view those orders will cause PHP level (uncaught) error.
