I went through the update process from 4.x to 5.x last night and had to make quite a few tweaks but got the desktop version working almost back to normal. I went to check the site on mobile (google pixel phone) and it’s not working at all. When you scroll down quickly you can see that it looks like the site is scrolling inside the header block and just has a white screen otherwise. Need some help to get this sorted out ASAP.
What’s weird is I can downsize the window in my web browser to the smallest setting and the site is fine on my desktop running that way. Admin Dashboard loads fine as well.
Turned off caching plugin and cleared all cache. Checked through as man settings as I could think of and still nothing.
Core is updated to 1.1.6 as well. Had issues with that initially and updated.
All plugins are up to date.
