certain drupal modules not working I've installed drupal several times and I'm still having the same problem. Some modules aren't working. 

E.g: 

Admin menu - They don't always appear. It only shows in random moments.

Wysiwyg and CKeditor - is not visible when I'm creating the content.

These are the modules I have installed and I'm using Marinelli theme: 


admin menu
Wysiwyg
IMCE Wysiwyg bridge
IMCE - this is for images
IMCE Mkdir
Pathauto
Chaos tools
insert
Mega menu
You might have a JQuery version conflict. Do you have the JQuery Update module? Or did you include some script not compatible with Drupal's version of JQuery?
