Blank white page Call to undefined function gettokenmanager() in Application.php

[sismail]

Hello,

I just updated my WHMCS first time to V5.3.14 from V5.3.13 & then I started to face blank white page same like Wordpress's White page of death. After a bit searching I found that I can troubleshoot further by adding "$display_errors = E_ALL ^ E_NOTICE;" I added this & now I'm facing this error:

 

"Fatal error: Call to undefined function gettokenmanager() in /WHMCS/includes/classes/WHMCS/Application.php on line 0"

 

I also tried to replace that Application.php with old one (from V5.3.13) but that didn't work & error is still here. Please assist me to fix that issue.

 

Thank you!

whenever this happens, upload the entire patch again to see if that fixes it.

Hey Brian,

Thank you for your response, I've already tried that & it doesn't work

it might be worth getting the full v5.3.14 download (not the patch) and doing a complete installation again with that.
