Run old plugins on version 4.

Contribute to this page

This plugin makes possible to run majority of old 3.x plugins on the latest TinyMCE, without any modification. However you need to take a few steps to enable it:

Installation Instructions

  1. Download TinyMCE development package.
  2. Copy compat3x plugin to your site.
  3. Copy utils and tiny_mce_popup.js to the same directory, where your tinymce.min.js resides.
  4. Load compat3x after TinyMCE core.
  5. (Optional) If you rename editor_plugin.js file to plugin.min.js then you will be able to load your old plugin as the regular one.

Type: String

Example of loading the compat3x before tinymce.init:

<script src="/tinymce/tinymce.min.js"></script>
<script src="/tinymce/plugins/compat3x/plugin.min.js"></script>
<script type="text/javascript">
  selector: "textarea",  // change this value according to your HTML
  external_plugins: {
    "myoldplugin": "/tinymce/plugins/myoldplugin/editor_plugin.js"
