Update, 1.7.10 is no longer supported here, and a mod will likely lock this thread once it's seen.

 

If you're sticking to such an ancient version because of mods that haven't been updated, you should harass the mod author(s) to update.

What version should I update to?

No, you should definitely not harass them to update.

I believe that version 1.9+ is supported on here now if not it is 1.10+.
