Anja, I found the problem. One of my text entries was causing the problem. I ended up deleting posts until I found the one that was causing the issue. Thanks for your help.

Thanks Wearitwell! I am a newbie to WP. Which file do I need to edit? I have looked through most of them and cannot find the line of code you mentioned above. Thanks again for your help!

Deleting the most recent post on the first site fixed that problem. I tried to do the same on http://www.growinginhisgrace.org but it didn’t fix it. I cleared cache and tried different themes, but it didn’t help. There must be either 1) something is to wide in my home page posts, or 2) a problem with code that only impacts the home page??? Any other suggestions??? Thanks again for your help!
