 * Hello,
    I have a problem. Until now everything was working perfectly, but suddenly
   this plugin stoped working.

 * Yop, there were too many plugins activated, and many of them were loading their
   own jQuery library, so there were several collisions… you have to load the jQuery
   just once (the main library like jquery, jquery-1.4.4, etc. just ONCE, others
   like jquery.cookies, jquery.easing etc. are not problem)

 * Thank you for your answer!!
    I just realized it’s a theme problem. If i put easing
   slider code in another theme it works. Here, [http://www.2aevents.it/](http://www.2aevents.it/)
   should be in the header.
 * **So what should i remove and from where?**
 * Thanks again!

 * You’ll need to remove the <script> elements that load jQuery in the various plugins/
   theme that are causing the conflicts. With WordPress, jQuery should be loaded
   using the PHP function ‘wp_enqueue_script( ‘jquery’ );’ rather than hardcoding
   the ‘<script>’ tag. However, a lot of plugins/themes ignore this and hence cause
   problems.

 * Or just try to turn off (deactviate) all plugins you don’t need.
    And UPDATE 
   every old version. After that, in my case, I removed just one jQuery library 
   in plugins directory… It’s not the best solution, but it worked to me and I didn’t
   have to search something in source code of plugins

 * I tried to deactivate some other plugin but it still doesn’t work =(

 * I’ve been trying to understand why in the theme that i need to use, easing slider
   doesn’t work, even though in another theme it works (without turning off any 
   plugin) and it seems it loads even more libraries than mine…
 * Can you help me, maybe looking at the source code?

 * You’ll need to do as I mentioned previously: remove the ‘<script>’ elements that
   load jQuery in the theme, and instead load jQuery using the function wp_enqueue_script.

 * It was mailpress plugin…I didn’t think about that because changing theme made
   it work.
    Anyway I reinstalled it and now both plugins work together!
 * Thank you for your help guys!
