If going to the profile page and clicking any button on the left below the tabs everything works as expected. But after that, clicking another button on the left opens the content in a new unstyled page.
On a fresh profile page there is no js errors. But clicking one button, the content loads in the div and then I see a js error:
jQuery("#spProfileForm").ajaxForm is not a function
And the url to the source just points to WP's native jquery.js in the includes folder.
Then... when clicking any button on left the unstyled content opens outside of SP in new window.
Occurring with WP's twenty-elevin and a un modded default SP theme.
Sorry for the vague report.... too much chaos going on around me. I can't WAIT until the kids are back in school!
