I’ve been struggling for few days to resolve the problem with “Updating failed. Non-valid JSON response message on the high of my web page.
The problem comes with the picture block and the icon field block from Gutenberg. Once I take away the blocks the problem is resolved. I’ve tried every thing I discovered on the web: deactivating all of the plugins, saving permalinks construction, modifying htaccess, whitelisting IPs and json paths…nothing appears to work. And what’s worse, I do suppose that the web page is updating, however the message is there.
can anyone assist?
the problem is linked with the next path : /wp-json/wp/v2/pages/115percent3F_locale=person and it will get 500 error code within the debug.
thanks
