# Jquery not executed after WordPress update

 * Hi all,
 * I was working on one of the pages of my website snaphunters.net for the last 
   week. Just yesterday I realised that multiple plugins stopped working properly
   throughout the whole website (e.g. smartslider3, a3 lazy load on [http://snaphunters.net/newest-pictures/](http://snaphunters.net/newest-pictures/)).
   Th plugins are used on the specific page so I am not sure when the problem occured
   for the first time.
 * I think jquery is not executed properly but I cant find the source of the problem.
 * First, I tried to narrow it down by deactivating all plugins.
    Deactivating smartslider
   is not solving the problem for lazyload. Deactivating everything except of Smartslider
   and Buddypress is also not helping.
 * The theme is highly customized by now. So I tried to use the original header 
   and footer. Nothing changed. I surely didn’t work in the functions.php in the
   last month.
 * The original theme skt befit is more than one year old but didn’t get updated.
 * How do I continue my search?

 * Hi [@dustinlichey](https://wordpress.org/support/users/dustinlichey/),
 * Firstly, are you sure it is a jquery issue? What is the exact screen/error you
   are seeing ?
 * There has to be some event that triggered the series of events that you have 
   observed. Did you update WordPress ? Since you are saying that the theme is highly
   customised, are you the only one making changes to this code?
 * Do you keep backups? If not it is always safe option to keep taking regular backups
   since this way you can roll back to a previous stable version.
 * In order to isolate the issue related to web hosting vs WordPress related, do
   you also face the same issue on localhost?
 * If you are seeing the same issue on localhost too, you could turn on WP_DEBUG
   and try finding hints of the issue there. To know more about the same read the
   following document:
 * [https://codex.wordpress.org/Debugging_in_WordPress](https://codex.wordpress.org/Debugging_in_WordPress)
 * Additionally, I would like to ask what makes you say that this is a jQuery related
   issue? What do you see in your browser?

 * You probably need some technical assistance from an experienced WordPress Developer.
 * You can start with using Google Chrome and using the Element Inspector – that
   will tell you where the problem is but then you’re going to need to know how 
   to fix it:
 *     ```
       (index):1660 Uncaught ReferenceError: TagCanvas is not defined
        (anonymous function) @ (index):1660
        i @ jquery.js?ver=1.12.4:2
        fireWith @ jquery.js?ver=1.12.4:2
        ready @ jquery.js?ver=1.12.4:2
        K @ jquery.js?ver=1.12.4:2
       ```
   
 * This is from “3D WP Tag Cloud-S: JS Functions” – it is breaking the JS and may
   be causing bigger issues

 * Hi Shannon,
 * Thanks for your reply. I also checked this before posting. The plugin was updated
   two weeks ago, which supports the thesis that it actually might have caused the
   problem.
 * However, shouldn’t simply deactivating the plugin solve the problem in this case?

 * Yes it should.
 * Are you using any caching software on your site? WP Super Cache? W3 Total Cache?
   Cloud Flare?
 * Deactivate it and try viewing the site in Incognito mode (Google Chrome)

 * I am not using catching software, because it doesn’t go well with buddypress.
 * Anyhow, I found the error. I was wring and it was indeed in the footer. The get_footer()
   function was missing.
 * Thanks for your help Shannon.
