Options page not found

I am working on setting up a new Wordpress site for the purpose of using Podlove to manage my podcast. When I try to submit the form on any of the ‘Expert Settings’ pages I am getting redirected to ‘options.php’ which shows an error page that reads “ERROR: options page not found.” From what I’ve been able to gather it seems that this may be related to the issue noted on https://codex.wordpress.org/Function_Reference/register_setting

Another possibility is the fact that I am trying to run this site on PHP 7 and I’m not certain of the current level of compatibility that Podlove has with that version.

Nice, Everything looks fine!

Podlove Publisher is compatible with PHP7 and should work as expected. Have you checked your web server error log files?

Yes, unfortunately even with debug logging enabled in PHP there wasn’t any useful information available. I am not at my computer at the moment but I am happy to post any logs that would be relevant.
