Thanks Maria, but that looks a bit too technical for me! Plus, I’m effectively using the older 3.9 version now. In fact, I just created two invoices earlier this evening. This plugin is simply fantastic!!! I’m sure the development team will find and fix the bugs in WP-Invoice. Thanks so much for all that you do!
I’m running PHP Version 5.4. I tried Anton’s recommendation to change line 161 to $wplt = new \UsabilityDynamics\WPLT\Bootstrap(); and, like jimmerd, it didn’t work for me.
So, I downloaded WP-Invoice version 3.9 and uploaded it to my website. That worked! So, I deleted 3.10.
If you need a copy of 3.9, you can get it here:
