Warning: Illegal string offset 'title'
Every once in awhile when sample content is imported the image data for the Hero BG Rotator does not import correctly. When this happens you'll see the following error "Warning: Illegal string offset 'image' in..." and similar listed a bunch of times on the front end of the site.
If this is happening, please go to your Dashboard > News Tickers > Hero BG Rotator and scroll down to the Images panel. There are most likely 3 fields added, but missing their thumbnail images. Click on the thumbnail image of each and select an image and then save your ticker. These are the images that will rotate as the background of your hero element. If there are more than 3 fields, delete the rest of the images so you have a total of 3.
