Can I be the first to say thank you for spending some time on the old donate-plus plugin.
You've made me very happy!!
One problem. Version 1.94
I did get one message when I activated the plugin: "The plugin generated 6 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin."
When looking at the donation page, have the options seems to be off the page and not viewable.
Same happened with 1.93
With 1.91, I had 3 characters of unexpected output. However everything still seems to be working with this version.
Had a few tests in Paypal Sandbox. I can confirm that IPN now works. :) :) :)
