Hi, has anyone had a similar issue with WordPress 7.0.3?

I have a custom plugin that works fine on my demo site (also WP 7.0.3), but on the live site its settings page keeps loading forever.

No PHP/debug errors. Other wp-admin pages work normally.

The weird thing is that if I open the same settings page with &noheader=1, it loads immediately. Without it, the request just hangs and doesn't even return headers.

So I'm guessing something is getting stuck during the admin header/hooks, possibly a conflict with another plugin or security/cache layer.
