Admin Page is blank

Using the latest version of zen cart.

I have gone through and read the tutorials on this problem, but I feel like I'm somewhat over my head.

What happened was, I had tried to install CKforEditor so that I could get an HTML editor for my pages. I felt when I was doing this that I might be missing a step. But I had backed up my files a day or two before, so went ahead with the module.

the store front looks fine, but the admin was blank. So I went and uploaded my backed up files, but still getting a blank admin page. I checked out the "cache" files, there are hundreds of documents in there. Furthermore, it seems to me that if the backuped files had worked, I would be missing the changes that I made last night. So I am just totally confused.

Any help would be appreciated.

I should add, I'm using Filezilla to do all of this uploading.

Just look at the newest error log file in /cache and post its contents here if it isn't clear what it's telling you.

All of the cache documents have a title of MyDebugAdmin, except the very first one, which has a title of:

sess_3da8442f9a830a02dde19f480cf755b4

The MyDebugAdmin files are all march 11. The latest says:

That CK editor, I'm willing just to forget all about that, and just do the best that I can with the plain text editor. I'm just trying to get back to yesterday at this point.

Temporarily delete that zest/includes/languages/english/extra_definitions/ckeditor.php file.

Then fix whatever is wrong with the file. See here: https://www.zen-cart.com/tutorials/index.php?article=87

And when you're done fixing that, be sure to rename your admin foldername since you've now shared its name with the world.

Thank you so much.
