  • Hi there,

    I’m the author of Seriously Simple Podcasting. I’d be interested to know why you think this is caused by a conflict with my plugin, especially because it never calls the is_plugin_active() function once. If you could offer more info on why you believe the conflict is with Seriously Simple Podcasting then I’ll see what I can do to fix it from my side.


    Hi Hugh,

    Basically I believe the problem lies with the latest Spacious Theme and not the SSP plugin. After rolling back to the previous version of the theme, the problem disappeared.

    I only got the aforementioned error when trying to view a podcast series (i.e. Archive page). The actual episode pages and podcast feed worked, as well as the rest of the website.


    Oh OK – then it definitely sounds like a theme issue. I’ll bow out as only your theme devs will be able to help from here on 🙂
