[TYPO3-english] typo3 frondend

[polycarp royal]

Hi all, I have a sudden problem with my frondend that throws the following exception  

ReferenceError: jQuery is not defined merged-169bfc3c2dbaf36638487242714982b2-17c67b11bb3021753fc53296d82f8a30.js:4

TypeError: $(...).slick is not a function 

Use of getPreventDefault() is deprecated.  Use defaultPrevented instead.

Have tried clearing typo3 temp folder and even all cahes but nothing happens. I'm using typo3 6.2.14
