4.7.4 is a nightmare for me. I’m stopping all future WP auto-updating until a version comes out that works, meanwhile I may have to just shut down my blog and walk away instead.
My custom header is gone and there is no option whatever to replace it, I’ve done every suggestion I can find, installed the few plugins that supposedly fix this, nothing works. The login function is messed up, it no longer keeps me logged in after checking the keep me logged in box. This is a caching problem that 4 tech on my service provider, Bluehost, have tried to fix and can’t.
When WP first tried to auto-update, it couldn’t because a plugin, Sticky Posts, was incompatible, so it corrupted Sticky Posts and the login function. This affects more than just my logging in, it prevented my readers from leaving comments as well because it required them to re-log in when they tried to comment, re-log in when they tried to return to the Home page….
Bluehost was able to finally delete all my plugins and install the 4.7.4 update, whereupon my header disappeared and absolutely nothing will get it back that I’ve tried… for 3 days, and I still have a caching problem logging in, I have to hit CTRL – F5, then it stays logged in.
