Custom post doesn’t work

@gmr1970 do you have a plugin that blocks REST requests or are you seeing and JavaScript errors in the developer console of your browser?

There are errors in the console:

Failed to load resource: the server responded with a status of 401 ()
blocks.build.js:1 Uncaught (in promise) Error: Request failed with status code 401
at t.exports (blocks.build.js:1)
at t.exports (blocks.build.js:1)
at XMLHttpRequest.h.onreadystatechange (blocks.build.js:1)

I deactived some options from iTheme Security and now it’s working

What could it be?

@gmr1970 I imagine there’s a setting that blocks the REST API in iThemes Security (unfortunately, I’m not all that familiar with it).
