Thank you for your reply.
Late last night, I deactivated my theme, reactivated it. I also deleted the MCB plugin and re-installed it, commented out line 69, and wrapped the “get_block” line in style="display:none"
and it started working after one time displaying the HTTP request error. Now it works. However – Now i have to figure out why it displays on ALL templates.
I will try to comment out line 89 & 90 like you suggested to see if that irons out any inconsistencies.
That being said, i really like the functionality of the plugin. Why it’s not part of core WP as an option, is beyond me. All the sites I’ve done on behalf of clients employ it. So, thank you!
