Thanks for pointing to the Health Check plugin. However, any troubleshooting attempts return similar error messages:
When switching the active theme to [default theme], a site failure occurred. Because of this we reverted the theme to the one you used previously.
When disabling the plugin, [any plugin], a site failure occurred. Because of this the change was automatically reverted.
…so either way the plugin doesn’t help address our acute feed issue as we can’t troubleshoot the RSS feed output.
