auto post – feed to database update but post not found on site

Hello

I have used this plugin for nearly a year and always updated it when updates came out, however after the recent update the plugin has stopped working.

so all my feets, categories and auto post settings are sorted. the plugin grabs the latest posts and places them into the database however the posts are no where to be found published on my site, when i click on the feed url i get a error 404 – e.g. if i got to feed list click on edit the view feed via the permalink url I hit a error 404?

Please help.

Thanks
Phil
