HELP!! Product description field in admin suddenly disappeared

Hey everyone,

Today i wanted to add a few new products to my store (online for over 4 years, not a new install or something)
When i go to add a product (or view one) all off a sudden the description box and the buttons for the text editor disappeared.
I have no errors in my log nor do i have errors in vqmod logs.
Haven't changed anything in the website like adding extensions or adjustments to core files etc.
I have been updating product descriptions about 3 weeks ago and didn't have any problems than.
The descriptions that were already stored are still working on the website's front so only the field in admin is gone/not showing.
Did a search and restored the ckeditor files from a backup from a few months back, from when i am certain it was still working.
This did not solve the issue.

Anyone have suggestions what to try/do to solve this or if there is any other place to be looking for error logs for this?

Thanks in advance!
Greetings Anton

I have found what is causing it just not yet the solution...
Few weeks back i got an ssl certificate and when disabled i see the description box, but when i enable it the box is gone.

In SSL Mode, one of your Scripts seems to be linked incorrectly, and so refuses to make the cKeditor work.
Check the Browser Source, to find out, what may still be linked to http:// in the header and eventually footer section.
I added a 'combined OC Code' file, regarding 'https', possibly, you could use some of the content, to make it work.
Good Luck !
