Error when set Unpaid invoice to Paid

[akboselk]

Hi

 

whmcs : 5.1.2

 

I just upgraded and everything working fine except below issue.

 

When I Try to Add Payment to Invoice by clicking"Add Payment" button (Please see attached image) it shows Blank White page as the result except showing correct result page

 

However invoice marked as PAID, BUT Next Due date not update correctly to Next year

 

This is not a template / browser cache and I removed all those as soon as I complete the upgrade

 

can anyone help to find the issue / fix this issue

 

Thanks

Got exactly the same issue Probably the worse thing that could happen to be honest, where's my 5.0.3 downgrade...

did you modify the pdf template ? "s/tcpdf_unicode.php o" generating the pdf seems to be the problem..
