Hi, I'm running the latest ISPConfig stable, and Rev 35 of the billing module, but I've been unable to send draft invoices since April (I only host a few friend's sites, so only generate invoices annually - hence I hadn't noticed) If I go to a draft invoice, it does have the correct items, but when I click on "Safe and Finalize", nothing happens. No error, no save, nothing. Any ideas where I can see what the error might be? It seems to be it's having an issue creating the PDF perhaps? Thanks in advance, Stuart
Yes, your PHP version is incompatible with the old Billing Module version you use. There have been various changes in the past years after your version was released to make the Billing Module compatible with PHP 8.x. The current Billing Module version is rev 43. You should consider to buy an update. Or you debug this yourself, if I remember correctly the issue is in fact the PDF template and also the tfpdf library must be updated.
Ah - given I only invoice about £50/year, it'd take me 2 years to recoup the costs - do you happen to remember the last supported version of PHP? I can downgrade the PHP version for ISPConfig if needed
