I expected to see: editable content in th vc text box (or any other VC element I attemptded to use
Instead, I got: No editable content, save button doesnt work. Chrome console shows Uncaught Reference error, using the latest toolset version. See screenshot
Are we talking about this problem:
Use visual composer to edit a content template of Views plugin, and add a "Ad" element, you see a JS error in screenshot: hidden link
I can see the JS error is from another plugin, seems to be "wp-seo", please check this in your website:
1) Deactivate other plugins and switch to wordpress default theme, and test again
2) Check if there is any PHP errors occur in your website
