Errors after update to the latest version and migrating from http to https

Hello,
After updating theme and all the plugins, i can’t edit content with TagDivComposer.
Moreover i moved website from http to https.
In console i see these errors (even if a i desable VisualComposer):
Failed to load resource: the server responded with a status of 403 ()

So WP editor doesn’t load, could you help me to solve this problem?

403 is a forbidden error. Means either the item isn’t there, or can only be served from same origin, or other issue.

You should first ensure you properly migrated to https before doing anything. Many tutorials online including how you would need to setup a default redirect for all queries from http to https version, redo any of your image and favicon settings in theme panel, search/replace your post meta dbase via phpMyAdmin/MySQL (or plugin that can search/replace dbase), for all instances of http => https for your domain name, and also perhaps explicitly put the https url for your site in wp-config.php.

Theme has no control over any of that.

You can check your error log also to see what errors you’re getting to help track down what you’ve not setup properly in your paths.

Basically a 403 error means something isn’t found, or trying to be loaded from someplace it shouldn’t (google ‘403 server error’).

I made all the changes, but still get errors and can’t load wpeditor.
Errors:
Uncaught ReferenceError: vc is not defined
Uncaught ReferenceError: QTags is not defined
Uncaught ReferenceError: tdConfirm is not defined
Uncaught ReferenceError: jQuery is not defined

Could you recommend me something to do?

Do fresh install; delete old folders, re-upload theme and plugin; resave permalinks, etc.

Double check your htaccess file is updated and removed any old caching or path setups. (Try resaving permalinks first.)

What if i can’t do reinstall? Website is already very big.
