Hello George. Or whomever reads this. I followed your advice and used the CUSTOM HTML block. My site will preview the infographic but it won’t publish it. Each time I try, I get a pink bar that says “The updating failed. This is not a valid JSON response.” I’d attach the screen shot but I don’t see that function.
Would this have something to do with my site’s firewall and security settings? My site got cyber-attacked in the spring and afterwards I purchased a firewall. If the Word Press site needs to talk to another site express the source code, could this be the problem? Please let me know if you know what the above mentioned error message means and how to address it. Thank you.
