Wordpress and TinyMCE Advanced: Failed to load javascript

When I change WP_PLUGIN_DIR example:

define( 'WP_PLUGIN_DIR', $_SERVER['DOCUMENT_ROOT'] . '/../wp-content/renamefolder' );

All plugins are shown and I can activate them.

But with TinyMCE Advanced when I wrote post, alert message shows

Failed to load plugin: insertdatetime from url ../../wp-content/plugins/tinymce-advanced/mce/insertdatetime/plugin.min.js

How to change code in tinymce-advanced.php or how to fix it?

WP_PLUGIN_DIR customizes the location of files in filesystem.

Most likely you also need to customize WP_PLUGIN_URL, which customizes client–facing URL location. If you omit this one, WP will decide it based on WP_CONTENT_URL, which might not at all point to your new location.

Another possibility is that plugin/code in question simply cannot handle a custom location. Generally this shouldn't happen under a normal WP API usage and such should be reported to developers as a possible bug.

I had the same problem an copied the en.js to de.js and voila - it works.

for some reason tinymce seams to ignore the language and defaults to en
