MyBB Community Forums

I'm trying to upgrade from 1.6.8 to 1.6.9 and when I go to url.com/install/upgrade.php, I am getting the "locked" error.

I tried following advice from here: http://community.mybb.com/thread-120752-...71643.html (deleted install folder and uploaded a fresh one) but that also didn't work. Any ideas?

Go to your "install" folder and remove the lock. This allows you to do the install and upgrade your forum.

So in your FTP for example;
public_html > install > delete the file called "lock." Looks like a blank page for the icon.

It has to be there, re-install myBB entirely.
