Thanks for the update.
Hey one of my plugins does what is called a Smoke Test to determine if plugins are compatible and works with the current versions of WP and PHP. Out of all my plugins (50ish), your plugin is the only one that fails both tests. The last version of your plugin that they tested was 2.8.2. I am wondering if the fixes that you did in version 2.9.0 addresses the issues that this site is showing?

At the bottom of the page you can click a link to view the test results of all versions of you plugin.
I don’t know how to request that they test the new plugin so not sure if your updates will pass or not.
Just wondering. Thanks
