Drop down user selection doesn't work

Hello im a beginner in concrete and i want to edit permission of a block but when i go to my block permission -> View Area -> Add, i can't select an user from the list because nothing is happening when i click on the button Select. Any clues why it's happening ?

i attach an image for you to easily see the button im talking about.

Do you have any javascript errors on your page?

When i open the console I see this (see attachments) but i don't know if there is a link with my problem.. may be possible ?

I know its my theme interfering with the button because when i put the page on the default theme it's work.

Thanks for the time !

It looks like your theme is including a copy of jquery, since the core already provides a copy of jquery when you're logged in this would cause issues. Try removing your copy of jquery from the theme and see if that resolves the issue.
