Theme Editor not Loading – WP 6.7.1

You mean a new theme or one of the themes that came with WP 6.7.1? The Appearance menu won’t look the same if you install a WP block theme.

Noticed it. This is the way you Customize a WP Block theme. If you are not familiar with block themes, which is the new trend, you have to study them. If you are not, install the plugins Classic Editor and Classic widgets and try another theme.

What you can see in the screenshot is an incomplete loading bar from the Site Editor. This looks like a server-side error, as something cannot be loaded. Have a look at the error log of your hosting. Your host’s support can help you find it.

@edby1980. Nice to know that your problem is solved. All the best.
