6.3.1 to 7.0.1 upgrade and everything broke :(

[liquidoxygen]

We just made a big mistake of upgrading from 6.3.1 to 7.0.1

Now everything is broken. Cron is not doing anything even we did everything as per the whmcs site.

 

We are not able to send invoice manually or download pdf.

Get this error

Fatal error: Class 'TCPDF' not found in /home/ussss/public_html/vendor/whmcs/whmcs-foundation/lib/PDF.php on line 0

 

We tried to fix the fonts using

http://docs.whmcs.com/PDF_Invoice_Customisation even installed the font, fix the logo.jpg etc but still it don't work.

 

 

In configuration.php we mentioned

$crons_dir = '/home/usss/crons/';

 

in

crons/config.php

we mentioned the exact path

$whmcspath = '/home/ussss/public_html/';

 

Can anyone advise on the this issue?

Thanks in advance.

Hello Liquidoxygen,

 

For your TCPDF please upload a fresh copy of the vendor directory to see if this helps.

 

With the Cron Issue are you getting any errors in the Cron Execution Reports?
