I am not sure what the problem is… i assume something within my WordPress is not installed. Could you check out http://www.markwilliammann.com and let me know what I need to do in order to fix the error on the right hand side under the "Recent Posts" section. Thank you!
Looks like PHP error, but I can’t tell from just looking what the problem exactly is. Maybe try and revert back to some provided code that is working and start over with your adjustments. I think that code is using SimplePie right? Maybe use the plugin instead of raw like I was using it:
check whats on line 25 of your sidebar.php, and see if you might have knocked any syntax off – its trying to figure out a foreach – which is something thats used within things like a loop to style each post. It looks like it might be something to do with the calling of each recent post title or info, the foreach being "for each post print this code". If that makes any sense..
It could just be as simple as you have knocked off a > or ? lol
