Recently we have chosen to upgrade our CMS systems to utilize the latest version of the TinyMCE WYSIWYG editor (v5). Not that the 4th iteration of the plugin was any bad, but keeping up with the times is always advisable and therefore ought to be followed. Of course one of the custom plugins that we’ve been using for quite awhile has stopped working due to the changes in the new editor. The plugin in question is ColdFusion File Manager for TinyMCE 4. Find the full step by step guide on how to upgrade the plugin to support the latest iteration of the TinyMCE.
