That must have been it — thank you!
If you started the import before rolling back to 4.5.3, you’ll need to clear out the BIE entries in your database. There are 3 in the options table.
It worked for me as well, but now it doesn’t jump to that section, so it looks like nothing happens when you click because the section with the links doesn’t fit in the window with the FAQ section. You can see the page here: http://elembee.com/work-with-me/. I only set the experience and design process links to have the expandanchor class — the links in the packages don’t have the expandanchor class and jump to that section but don’t expand. Any thoughts?
