I am trying to: Insert shortcode via "Fields and Views" button in Content Template
I expected to see: the shortcode inserted after clicking "Insert Shortcode"
Instead, I got: a greyed-out screen with a "0" showing (highlighted on the screenshot). All that can be done is to click on the page, which restores everything to the way it was before.
I am able to manually edit the Content Template and save without issue. And I can also insert via the CRED Forms, Media and Grid buttons. The problem seems to be related to the Fields and Views button only.
Shane, thank you. I figured it was a plugin conflict but thought I'd submit the support request anyway just in case it wasn't.
I have isolated the issue to a specific plugin. At the moment I think the best next step is to contact that plugin's developer. Depending upon what I find out I might bring new information back to you.
