Running into an issue when upgrading the TinyMCE plug-in from v1.2 to v2.0.1. The install seems to go okay, but after it completes, an error shows up:
Fatal error: Call to undefined function sp_tinymce_do_upgrade() in /var/www/mysite/wp-content/sp-resources/forum-plugins/tinymce-richtext/sp-tinymce-plugin.php on line 88
Running WordPress v3.5 and SP v5.2.
