Hey, I saw a lot of comments about WP failing to upload zipped theme. I also tried all the fixes out there — no joy until I went simple! I unzipped the theme folder (enfold.zip), then FTP’d the enfold folder to public_html / themes. Went back to WP control panel, and voila — Enfold theme available.
Also…if you’re using FileZilla … looks like version 3.10 is busted – always timed out regardless of tweaking. I downgraded to 3.08; works like a champ.
Cheers and be well! Mark
