Podcast Episode info not saving

Hi. We’ve been using your plugin for a while now and it’s been working great.

But it seems like the podcast isn’t getting submitted to iTunes now. We noticed something was wrong when we created a blog post and entered the podcast info in the Podcast Episode box, and saved it as a draft. The info that we enter in the Podcast Episode box didn’t save. When the page reloads the info in that area gets reset. Everything else saves – the post title, the text in the text area, featured image, category, etc. only the info in the Podcast Episode box is not saving.

We tried publishing instead of saving as a draft and the same problem happens – the podcast info isn’t retained.

I turned off all plugins besides the powerpress plugin and activated the Twenty Nineteen plugin. I alos updated to the latest version of the plugin and also version 5.2 of WordPress.

This is what it says on the Blubrry PowerPress Diagnostics page:

Your web server supports the PHP cURL library. Your web server is also configured with the php.ini setting ‘allow_url_fopen’ enabled, but the cURL library takes precedence.

You are able to upload and save artwork images for your podcasts.

The following test checks your version of PHP, memory usage and temporary directory access.

WordPress Version 5.2

Your version of PHP (5.6.40) is OK, though PHP 7.0 or newer is recommended.

You are using 2% (5.3M of 256M) of available memory.

Temporary directory /srv/bindings/672724d88b594ac8b2910ff64f3a669b/tmp/ is writable.

Warning: PHP running in CGI mode.

Any help would be appreciated. Thanks
