# Uncaught ReferenceError: tinyMCE is not defined, plugin error

 * On my WP multisite I have a plugin that days ago it did work but not now, indeed
   on dashboard when I press the form button “save settings”, from chrome console
   I get **“Uncaught ReferenceError: tinyMCE is not defined”**.
    Ok so the problem
   could be another plugin that interferes with this one and the possible solution
   could be deactivate all plugins and reactivate one by one until find out which
   one interferes…but it’s a good solution? Is there a possibilty to simply adjust
   the plugin that doesn’t work instead of deactivate others? these are my errors:
 *     ```
       t.getFormParams
           (anonymous function)
           m.event
           r.handle
       ```
   
 * and this is the reference for the admin.js?ver=1.5.4:836 error of t.getFormParams:
 *     ```
       case "editor":
       					if(tinyMCE.get(name) != null){
       						value = tinyMCE.get(name).getContent();
       					}
       				break;
       ```
   
 * and the admin.js?ver=1.5.4:1187 referencec for the (anonymous function) error:
 *     ```
       var data = {
       				name: jQuery.trim(jQuery('input[name="name"]').val()),
       				handle: jQuery.trim(jQuery('input[name="handle"]').val()), //is alias
       				postparams: t.getFormParams('eg-form-create-posts'),
       				params: t.getFormParams('eg-form-create-settings')
       			};
       ```
   
 * Is there someone who can guide me to solve and understand what’s the problem 
   and how to fix it? How could I define tinymce? How to search into the php code
   of the plugin?
 * _p.s.
    I don’t understand the t.getFormParams error I got, cause I’m the administrator.

 * Deactivating all plugins and re-activating them one by one is not a solution,
   but will let you determine which plugin is the cause of the issue. Once determined,
   you can decide to replace it with another, contact the author for a fix, or try
   to fix it yourself.

 * and that’s the point…I wish to know how is it possible to understand where the
   problem is. Once I understood which plugin make the issue, where I can see exactly
   the error? I need to debug, or what?
    Thanks

 * most likely the plugin is causing a JS error. check the console in your browser’s
   developer tools.

 * I don’t understand the process…what about those errors I wrote here above? They
   are generated by wordpress for let you know that something is wrong, but without
   telling you what?

 * The JS errors are generated by your browser, not by WordPress. If you want to
   fix them you’ll need to track them down and figure out the issue.

 * Thanks karpstrucking,
    now it’s much clear…so maybe the best solution is to subscribe
   for a service to track js error, I saw some website online. There are also few
   plugins that do that, but I don’t think are a good idea. What’s you’re point 
   of view?
