Richtext editor not visible in admin panel
I have checked everything nothings wrong but still can't find what's wrong
Here welcome_text and service_text for example. All pages with text editor shows same error

It happened to me once.
If I remember correctly, downloading the latest version of CouchCMS, and making sure you are replacing the "includes" folder should do the trick. If not, try replacing all files for the latest ones available.

Good luck!
