Simply because the Feeds are not updated, just go to your Feedburner account, under the “Publicize” tab, you will see a left links, find “Pingshot” and activate it. That option will tell the other services about your feed update.
If for any reason the feed still the same, then find “Troubleshootize” tab. in your Feedburner account, scroll down and find the button “Resync Now” click on it, and it’s done.
(if you’re using a caching plugin, delete the cache)

You don’t have to edit anything,the best feed format is the one I suggested http://feeds.feedburner.com/mrsmurphyslawoffitness click on it and you will get your working feed page from Feedburner. The problem can be caused by programs who can’t work properly with some format of feeds, this seems unusual but it’s the truth.
Now, all you have to do is replacing your old feed used in the bloglovin.com by the new one, that’s it. Their system will read your images correctly after your next post.
(by the way, URL feeds are not for browsers only,but people should see them when clicking the link,it’s the only way to subscribe to the feed using their emails.)

If this is your first WordPress installation, clear your browser cache and try with Firefox, it happened many times with Chrome.

Your Feed is wrong, this is the right one

Please change your browser, try with Firefox or IE, at the same time change your actual theme to one of the default WordPress themes, if this can’t solve the issue, then you need to contact your hosting provider.

Switch browser and verify if it works, if not than verify the “uploader” file permissions, set it to 777 and upload any image to see if it works. if you get n error message you can add it , so I or anyone else can help here.

You don’t have a problem with the plugin,your theme will show ads and recognize the plugin if you use the php code and not the id group (in the theme). To implement the ad group, you have two ways:
1/ In pages
You need to add your group ID code like this [adrotate group="1" ,you can add that short code anywhere in pages, posts and widgets, but it won’t work in the theme.
2/ In Theme
The second way that work with your theme is using the php code, just click on your group name, scroll down to find Usage when you will see the group php code to use (it’s something like <?php echo adrotate_group(1); ?>), the best way to implement that php code in your theme is installing the “Genesis simple hooks” plugin first, then insert the php code anywhere you want and don’t forget to check use php box.
