$(...).flexslider is not a function jquery flexslider not working

Are you facing JavaScript flexslider error "$(...).flexslider is not a function" or jquery flexslider not working?

If jquery flexslider is not working or showing error in console ""$(...).flexslider is not a function". 

If you do not want to see this error "$(...).flexslider is not a function" then use one instance of jquery.js file and keep in mind do not use defer or async keyword in below 3 files:

1- jquery.js

2- jquery.flexslider-min.js

3- jquery.prettyPhoto.js --> *if you are also using this file.
