Did you clear your browser cache after updating?

Yes I cleaned the cache.
correction: The issue about the 'small listboxes' is only occuring in IE. I tryed it on different PC's.
The duplicate in the security-tab are visible in IE, Chrome and Firefox on all tested pc's.

What IE version?

I can reproduce this with IE 11.

Denis, I have pushed a fix for the wrong text.
Can you have a look at the IE display issue (since you changed all select boxes to use select2).

I didn't update to select2, i just fix some CSS for seelct2 (min-width ...)

But i have a look .

@sammousa : Yii Booster seems to have big update since 2013 :
You use https://github.com/clevertech/YiiBooster directly or an updated version?

Because application.extensions.bootstrap.components.Bootstrap is replaced by application.extensions.bootstrap.components.bootstrap.

Are there an easiest than update all alias ?For 2.06, think develop don't need it.

Thinking of add a new Extension, something like Bootstrap extend Booster ...

PS2: i test with Yii-Booster 3 (last 2.X version of bootstrap) actually. Need to test on VirtulaBox for IE10/11 then if it's OK : pushing it tomorrow.

Alternative is to find all Boostrap call and replace to Booster call.

Yii-Booster 3 don't fix the issue. Try to update the width when tab is shown ...

Different system for 3.0 (select2 is up to date)
