Preventing edits on posts and pages. Read through alot of post.

Here is what i have done:

2. clean browser cache

3. Enabled TinyMCE, cleaned cache and still have the issue
4. Do a ctrl + Shift + J and get the following error.

Uncaught ReferenceError: tinymce is not defined – plugin.min.js:1

Uncaught ReferenceError: tinymce is not defined post.php:1948

I have uninstalled the plugin and upgraded to 5.7 and have the same issue

With the plugin removed, doing a ctrl +shift+J, I still get the above errors.

I was hoping removing it would remove everything but it has not. I still see the reference to tinymce

I see the refence in Chrome Deve tools to post.php?=2&action=edit

I also see plugin.min.js:1 refence this in chrome deve tools

var init, id, $wrap;

if ( typeof tinymce !== ‘undefined’ ) {
for ( id in tinyMCEPreInit.mceInit ) {

$wrap = tinymce.$( ‘#wp-‘ + id + ‘-wrap’ );

if ( ( $wrap.hasClass( ‘tmce-active’ ) || ! tinyMCEPreInit.qtInit.hasOwnProperty( id ) ) && ! init.wp_skip_init ) {

If its removed how can this be in the code.

Any help would be greatly appreciated

Thank you
