Verify_Security_Token error after upgrade

[Carly1]

After upgrading to 3.7.3 when anyone replies to a thread they receive this message:

Fatal error: Call to undefined function: verify_security_token() in /home/****/public_html/forums/includes/init.php on line 410

(I uploaded init.php from an older 3.7 version and it let the reply through, but there were other errors also)

I've disabled all plugins and that didn't help anything...

TIA

I responded to your support ticket:

That function is defined in: includes/functions.php

Toi fix this you neeed to upload the original 3.7.3 file. And since this one was not uploaded correctly there are probably others as well. To troubleshoot this, first reupload all the original vB non-image files (except install.php). Make sure you upload these in ASCII format and overwrite the ones on the server. Also be sure to upload the admincp files to whichever directory you have set in your config.php file.
