# Search function not working – Javascript TypeError: “x” is not a function

 * Hello
 * I have installed the Ivory Search plugin and it works on every page except the
   home page. When I click on the search icon, the link simply doesn’t work.
    If
   I deactivate the old slider plugin on this page, the search plugin does then 
   work, so I have been told this may be a conflict with loading an old JQuery library.
   Unfortunately I don’t know enough about JQuery or Javascript to know how to resolve
   this. I did look at the Firefox developer console and got a couple of errors 
   up saying ‘TypeError: $(…).on is not a function’. The site is using the latest
   version of WordPress but both the theme and the slider plugin are fairly old 
   now. Any suggestions of things I could try very appreciated.

 * To rule out a plugin/theme conflict, try:
    – deactivating ALL (yes all) plugins
   temporarily to see if this resolves the problem (plugin functions can interfere).
   If this works, re-activate them individually (one-by-one) to find the problematic
   plugin(s). – switching to the unedited default Theme (Twenty Twenty, etc.) for
   a moment using the WP dashboard to rule out any theme-specific issue (theme functions
   can interfere like plugins).

 * Many thanks for your advice [@t-p](https://wordpress.org/support/users/t-p/)
   
   I’ve concluded that the slider plugin is too old and this is causing the problem.
   Appreciate you taking the time to reply. All the best.
