Editing is not possible after the WordPress 7.0 update

    Hello, I have GP Premium and GenerateBlocks Pro. Since updating to WordPress 7.0, I can no longer create or edit posts.

    I can only see the sidebar; the content area is just grey. When I click on ‘Add Block’ or select an existing element, the central area remains completely blank.

    I would appreciate some support.
    Kind regards,
    Beate Bodendorf

    Hi Beate,

    Can you try temporarily deactivating all plugins except GP Premium and GenerateBlocks to check whether this might be a plugin conflict issue?

    Let us know if the issue still exists when only GP Premium and GenerateBlocks are active, then we can troubleshoot further.

    Hello Alvind,

    I’ve just deactivated all plugins except GenerateBlocks, GenerateBlocks Pro and GP Premium. I then deactivated the child theme and activated GeneratePress.

    Unfortunately, the error I described was still appearing afterwards.

    Hi Beate,

    I checked the issue, and this does not appear to be caused by GP Premium or GenerateBlocks Pro.

    In WordPress 7.0, the Block Editor loads the main editing canvas inside an iframe. On your site, that iframe is currently being blocked by the site’s Content Security Policy (CSP) header. That is why the editor sidebar still loads, but the main editor canvas appears blank/grey.

    The browser console error indicates that the CSP is blocking a blob: iframe used by the WordPress editor. This is typically controlled at the hosting/server level, or wherever your HTTP security headers are configured.

    Please ask your hosting provider to update the Content Security Policy to allow blob: frames for the editor, for example:

    
frame-src 'self' blob:;
child-src 'self' blob:;

    Once that change is applied, the Block Editor should load normally again.

    Let us know how it goes.
