Argh, me too. 4.2.3 broke my Theme (Themify’s Landing)
I think I’m going to install the previous version, 4.2.2 (found in the archive). Any reason why I shouldn’t do this? I’m new to all this.
Also, I installed the Easy Updates Manager plugin and disabled all automatic updates so this won’t happen again. Again, any advice on why this would be a bad idea is appreciated.
