In my theme editor, I get this error with "header" and "footer". There is also this error: "Error loading block: You are probably offline.".
Additionally, when trying to save an action in my theme editor, it fails with an error.
Disabling wpdiscuz resolves this issue. I have no other plugins installed, only wpdiscuz.
I tried purging my WP install and starting from scratch. Same issue.
Clearing my browser cache (or using a different browser) did not help either.
The only 'unique' thing to my site is that I have 'WP_HOME' and 'WP_SITEURL' hardwired in my wp-config.php, per the instructions here: https://developer.wordpress.org/advanced-administration/upgrade/migrating/ .
Any help is greatly appreciated.
Thanks
