I have installed the JWplayer module from https://github.com/silverstripe-labs/silverstripe-tinymce_jwplayer by putting the folder in my sites root.
this gives a fatal error when reloading admin or running dev/build:
Fatal error: Call to undefined method HTMLText::register_parser() in /Users/willbarker/Dropbox/msp/jwplayer/_config.php on line 2
Have i done it wrong? think so. is there a missing installation step? and how do i use the module once its up and running?
