Hi,
Hi,
I can not access your site now.
Also, I have tested on our demo site with the latest version of the Plugin and WP 5.0.1 the widget still works fine. I don't think this issue come from the Plugin after updating.
You can check our demo: https://demo.gavick.com/wordpress/university/
In your case, you can try the following solution:
1/ go to cPanel of your GoDaddy account
2/ open File Manager
3/ browse to the rtMedia folder
4/ in the File Manager, right-click on the folder.
5/ select Change Permissions
6/ select following checkboxes
a) user - read, write, execute
b) group - read, execute
c) world - read, execute
Permission code must display as 755
Click change permissions
Hope this helps!
