CMS Made Simple Forums

Running - CMSMS 1.10.3

For the life of my I cannot figure this out.

In the "options" tab while editing a page I cannot get the thumbnail drop down to display.

The only "exotic" configuration I have is I have all of my upload/image directories on an external "assets" domain..

The file/image manager works fine for browsing and uploading.
The Content_Image tags works fine.

Even the Image drop down in the "options" tab works fine.

Any help would be greatly appreciated.

It is looking for files with thumb_ prefix which the image manager in CMSMS makes...

I am an idiot.
Always the simple answer.
Thank you sir.
