https access

As a matter of practice, I access the administrator panel of my Joomla sites via the secure link provided by my hosting provider. For example, if my site is located at

http://xxx.yyyyyyy.com/~preview/sitename/

I would access the Joomla admin at

https://xxx.yyyyyyy.com/~preview/sitename/administrator/index.php (note the https)

After upgrading from EB 3.9 to 5.0.14, I can still access the EB admin, but nothing saves to the database. For example:

- I can't save edits to existing blogs or create/save new blogs (no saved message displays)
- Checking for Updates feature icon on the Dashboard hangs (does not show current version)
- The Database sync doesn't run

In addition, I get the following error on the admin page (Dashboard) in the browser debugger:

POST https:///xxx.yyyyyyy.com/~preview/sitename/administrator/?option=com_easyblog&_ts=1436456389427 404 (Not Found)

n.ajaxTransport.send @ admin-5.0.14.static.min.js:150
n.extend.ajax.v.send @ admin-5.0.14.static.min.js:144
(anonymous function) @ admin-5.0.14.static.min.js:288
(anonymous function) @ admin-5.0.14.static.min.js:269

If I access the admin using an unsecure link (which I was able to do with EB 3.9 and need to be able to do again) the EB Dashbloard works and I am able to save and edit posts.

What do I have to do to be able to access the EB admin using the secure link for the Joomla admin that I've always used?

Thank you.
