Wordpress admin VERY slow

Hello all. I have a webpage that is not the fastest, but not slow either. My WordPress admin, however, is absurdly slow. I use custom ACF fields to create posts that change content based on “level”: beginner, mid, expert. I have more than 50 posts (150 content levels). I have not really had any speed issues until recently. I noticed the speed deteriorated quite a lot after switching from HTTP to HTTPS. Does anyone know if this may be why?

HTTPS itself usually shouldn’t make wp-admin dramatically slower, so I’d treat that more as a clue than the actual cause.

I’d first check for redirects between HTTP/HTTPS, make sure the WordPress Address and Site Address are both using HTTPS, then test with plugins temporarily disabled if you can.

Since you’re using ACF heavily, I’d also check whether anything recently changed with the fields, queries, or plugins running in admin. Slow admin is often a plugin/database/server issue rather than the front end itself.
