Hey there! I’m so sorry to hear that happened to you! There are about 100 other websites using Tip Jar WP daily to process tips and donations successfully, so it looks like something unique happened in your case. I would love to help you get that resolved!
It sounds like your server may be running an old version of PHP, or perhaps WordPress, or maybe even both.
Tip Jar WP requires PHP 7.0 or later. If you are running an older version, this could happen.
I will be happy to work with you on resolving this in our support forum here on WordPress.org! Let’s get it working for you!
