XF 1.5 Title error

[MirandaSings]

I am having this issue where I can't make have 1 more than capital letter in a thread. I tried editing the title, but it won't let me put anymore than 1.

Why is this?

You probably have "Automatically Adjust Case of Discussion Titles" switched on and set to Sentence case. Use the ACP for "sentence case" to find it, then change to Title case or switch it off depending on what you want.
