Call to undefined method vB_Friendly_Url_Error::get_url()

[donjuevas]

I just recently upgraded to 4.1.6 and I'm getting that specific error message on every page. Here is the exact error with private server-specific paths removed:

Fatal error: Call to undefined method vB_Friendly_Url_Error::get_url() in /path/path/path/includes/functions.php on line 7226

Before I upgraded I backed up the database, turned off plugins, uploaded everything contained within the upload folder except for the install/install.php file. In other words I followed the instructions. At the end of the upgrade process it shows me the two buttons, one for the admin CP and the other to view the upgrade log. The admin CP (nor any other URL) on the site work (except obviously some of the random HTML pages I have in other folders outside of the forum structure). I have viewed the upgrade "log" (what I'm referring to is the thing on the upgrade page itself) and I see no errors or anything.

I didn't modify any of the files. I uploaded them all to the correct place.

I posted on the customer support system and the guy said it sounded like perhaps some of the files didn't upload or that maybe they didn't upload correctly. I have at this time uploaded and reuploaded the files 6 different times, telling CuteFTP to overwrite. I have run and then rerun the upgrade. I have this same result every time.

Can someone please, please help me out?

On my server error log all I see are the same fatal errors. There are no include files missing or anything like that.
