If you have recently upgraded WordPress and found your theme a bit under the weather then you may have been a victim of “jQuery update”. This is what I am calling it. The simple solution it to look for all of the “$” DOLLAR signs within the<script> tags and replace them with “jQuery” (For all of the novices reading this please do not use or acknowledge DOUBLE QUOTES like this “. Only use what is inside the DOUBLE QUOTES.) This is a safety feature WP uses called no-conflict. You can read more about it here: http://codex.wordpress.org/Function_Reference/wp_enqueue_script.
Happy code hunting:)
