Thank you for sharing all the details Jeff, however, I’m afraid I can’t answer your question. While we are more than happy to help you with any problems you might encounter with the plugin’s functionality, we cannot answer any questions in regards to what is in the logs. We do not know your website as you or your web host do, so that is a problem that you have to solve.
As per my previous post, check all the processes you have running on your website, all the plugins, the theme and any other software you have, check all the logs etc and do an analysis to find out what the issue is.
In regards to the time in the logs, from the plugin settings you can configure the plugin to use either UTC or the timezone configured on the website. To change this navigate to the Activity Log viewer tab in the plugin’s settings page.
I hope the above helps. Please let us know if you need any further information.
