admincp "New Forum" Options missing?

[Shinkaze]

UPDATE I am also receiving an "illegal string offset" error when I use the create new channel based on previous channel option (see 4th post screen shot)

I have a reasonably fresh install of 5.1.1 (no community only a couple of admins and still setting up styles etc). I went to create a "Forum Link" by going to
Admincp>Channel Management>New Forum
And noticed that a majority of my New Forum Options are now missing? (Forum Link included). What happened?

PS when I posted this thread I got a Database error. It appears to be related to the screenshot I attached which is not showing up in the post above. I will make another attempt to post the screenshot next.

"Illegal String offset" when I use the "Create Channel Based on Channel {combobox} {GO}"

We are on the verge of launching this forum, and I am awaiting feedback on this error before we choose to continue with this build or look at other options.

What is a way to resolve this?
Is this connected to the original issue where the forum options have vanished?
