It's fully upgraded/updated as of today. I logged in and received this error...

Then, I went to studio and found that the system was upgraded automatically overnight to 10.0.0 B2 and all of the modules were updated as well.

I'm sure I messed up a setting somehow, somewhere, but I don't know enough about it to know where or how. I did this a long time ago as I was first setting up the aesthetics of the site. At that time, I changed some things on the splash page, but it works fine. Otherwise, I only changed things within the program until this upgrade when I changed a line of code to allow upgrades to beta versions. I also chose to force auto-updates even if some files were modified, in hopes that it would overwrite these header errors with updated files.
