Extension is not correctly loaded into Frontend Typo3 7.6

[jpenaico]

Hi,

I configured and installed the Extension like in the Typo3 Online Manual.
Created a Page where I want to show the Keyword List.
Choosed the "Special Menu" Content Element and added an internal page which definetly has keywords.

Having done these steps I looked up the Frontend and got this error

Error: The jQuery library has to be included (Hint: use page.includeJS)"

I could fix that by including the Extensions Javascript after Jquery inclusion.

The first Error is gone but now I only see a simple unsorted list Element with the Link to the page.
No jumpmenu with A-Z nor any Headlines and the actual Keywords contained in this listed page.

What did I do wrong?

I'm using

• Extension Bootstrap Package 7.0.2
• Typo3 7.6.15
• PHP 7.0.13
