I tried to upgrade to version 1.5.10 and it gave me PHP errors. So on the advice of the hosting company (a2hosting) I did a fresh install of 1.5.10.
Even with the fresh install, InvoicePlane does not work unless I change the PHP version to 7.3.
This is what I get when I am on version 7.4
A PHP Error was encountered
Severity: Core Warning
Message: Module ‘sqlite3’ already loaded
Line Number: 0
Is there anything I can do?
