Hi everybody,
I tried roll back to old database version, no luck.
I resolved by replacing my public_html directory to its last working version "1.7.8.5" and the error disappeared, luckily I had it.
I guess there's a bug in the "1.7.8.7" or it just doesn't fit with my hosting.
Database remains the upgraded version so no roll back was made.
I am on a2hosting dedicated Turbo + LiteSpeed Cache + LiteMage:
