Why does the block settings (admin panel) in drupal break when the module is enabled?

Question

Drupal

Enabled the jQuery Update module. The block settings on the site page disappeared. Well, those same gears where the settings, editing. This module is needed in order for fresh jquery to be included, since the site is old.
Has anyone come across this, or should I use a separate version of jquery for my own needs?
Error in console

Uncaught TypeError: Cannot read property 'msie' of undefined

Answer 1

Try selecting an older version of jQuery in the jQuery Update settings. It may be that the theme simply does not support the latest versions.
