Have completed a fresh new install of Moodle 1.9.5+ (Build:20090812).
Everything has been working without any problems until I tried to enable the Multimedia Plugins.
Upon clicking the Closed Eye under Disable/Enable for Multimedia Plugins on the Manage Filters screen I am taken to a new page with the following error message.
Filter filter%2Fmediaplugin is not currently installed
This same error message appears for any Filter that I try to enable. The only difference is that the name of the Filter is shown after the %2F.
Eg: Glossary Auto Linking ----> Filter mod%2Fglossary is not currently installed
I have not installed any other modules or plugins. This is a stock standard default install.
Any help greatly appreciated.
