Site editor not loading from backend

Temporarily switch to the Twenty Twenty-Two parent theme to check if the issue is related to the child theme. If the problem disappears, the issue might be in the child theme.

Turn on WordPress debugging to see if any errors are being logged.

@yujesh thank you for your reply. Switching to the default theme did not help. I set debug mode to true in wp config and tried to open the editor again and than looked for the debug. log in wpcontent but there was no debug log. Am i doing something wrong?

@t-p thank you for your reply. I tried out what you suggested but it did not fix the error.

Try looking in the JavaScript Console to see what it says: https://developer.www.ads-software.com/advanced-administration/debug/debug-javascript/

If errors are reported there, please show a screenshot or code block here.

@threadi , i posted the screenshot. To my understanding it looks like the plugin wp optimize causes the problem. (wpo minify footer). The stange thing is that i deactivated all plugins before and the problem persists. I have also disabled minifiing in wp optimize but also tha the problem persists.

This is the view of your frontend, and yes, WP Optimize has some kind of problem there. But that probably doesn’t matter for the block editor. Can you show a screenshot including the JavaScript console of the state you see after clicking on “Edit page”? Because that’s what you’re talking about.

@threadi i also made a screenshot while logged out and that gives this result (screenshot)

@threadi this is a screenshot while opening the editor

In the last one you can see the reason why the editor does not load: it has to send several requests to the server to display data. Two of them are answered with 405 – i.e. “not allowed”.

Based on your other checks, many things can already be ruled out. Please have a look under Tools > Site Health to see if any anomalies are mentioned there. My guess is a server-side problem, which should also cause messages there. It is best to contact the support of your hoster.

@threadi i installed the health check plugin but i seen no errors. I’m not sure how this plugin works though

@tom-pijnenburg out of curiosity, if you trying and click around to different sections of the Site Editor from the panel on the left, does it eventually load?

@ndiego thank you very much, i didn’t try that but it does work indeed. I can live with that. Thank you.

@ndiego Styles are unaccesibly unfortunately

Thanks for the update. I have shared this issue in WordPress Slack to see if anyone else knows what might be causing this.
