Hi, I am having javascript issues on most admin pages. I can edit modules content and settings without problems, but:

If I access Admin/UserAccounts and try to delete a user, I the page refreshes with the user still existing and the dropdown boxes displaying incorrectly.

If I try tu update the site settings, I get a "cannot read property 'options' of undefined javascript error and the page reloads with again the dropdown boxes not displayed correctly.

Similar thing happens on host settings, etc.

Any idea what could cause that? I am using 7.4.2 and local jQuery.
