Invalid command 'application/schema+json', perhaps misspelled or defined by a module not included in the server configuration

Hi Jay,

First of all - maximum appreciation for you giving the community a free guide on htaccess files for Wordpress. It's greatly appreciated :D

However, it's probably my server being a jerk - but I'm seeing the following in my apache logs:

Invalid command 'application/schema+json', perhaps misspelled or defined by a module not included in the server configuration

Do you have any knowledge on what would be causing this?

I believe this could be a potential fix:

Plesk recommended AddOutputFilterByType DEFLATE syntax

@michealjroberts Sorry about my delay replying to this. Did you find a resolution? If not, I'd recommend trying commenting out sections until the error disappears to find the offending piece of code. When you find the section, let me know and I'll take a closer look.
