Most probably this should be an issue with you theme or some other plugin might be conflicting with AIOSRS's jQuery.
Try this -
# Please disable all other plugins except AIOSRS temporarily and see if things work
# If not, temporarily switch to any other WordPress theme to check if the culprit is in the theme
Still no luck? Other case, if plugin files are not downloaded / installed on your server properly -
1. Deactivate & Delete the "All in One Schema.org Rich Snippets"
2. Re-install latest version of the plugin & activate it.
3. Clear your browser cache. (How to guide - http://kb.iu.edu/data/ahic.html)
4. Deactivate the plugin & activate again.
Please let me know what happens :-)
