Hi borgeolsen,
Thank you for using my plugin. I’ve seen similar issues before. I can’t tell 100% just from a screenshot, but that looks like there’s some extra html being added in there — not by my plugin but by something else… possibly another plugin or the theme itself. To narrow down the problem you’ll have to do a bit of troubleshooting.
* Disable all other plugins and see if the text returns to normal.
* If it does, turn each plugin back on, one at a time, and see which one causes the issue. Once you find that, contact the developer for assistance
* If it does not, change the theme to something different (such as twentytwelve) and test. Assuming the issue goes away upon changing the theme, contact the theme developer for assistance
