Do you have any clue where I could look, or is it different for each theme?
It’s different for each theme. You can search text files using the search function in your operating system.
Can you give some more information such as which theme you are using that is causing the output in your footer? If you switch to the default theme (twentyten or twentyeleven) does the output text still show?
I’m using the real estate part of “OpenHouse Realestate 3.0 by BuchmannDesign” theme.
There’s so much customizing on this project that I am afraid that switching will delete it.
This is a premium theme, so you can ask the theme developer for support.
I figured out the problem. The culprit is a plugin called Reveal Template. I have no idea how this plugin was installed. I did not install it and it did not come with the WordPress 3.1.4 installation. Weirdness!
