[SOLVED] all pages of my site end with ?tmpl=component

Hi and thank you for the help.

I have Biz template.
I don't know if it came from Rocket module or from extension that I installed.
All my page links end with ?tmpl=component

Ex. www.around-naples.com/en/history-naples.html
has a duplicate page:
www.around-naples.com/en/history-naples.html/?tmpl=component

How I can fix this issue. Bing instead off indexed 46 pages has indexed the double 92.
I thought to insert line on my robot.txt
Disallow: / *?tmpl=component
May I do that or I will make some mistake?

Thank you in advance.

?tmpl=component

is only available if you open the roksprocket in a popup.
You can select another style in roksprocket module, without popup

Thank you for your quickly reply.
But I didn't found solution.

I also disabled all my roksprocket modules but the link continue to appear if I add this ?tmpl=component

At beginning I didn 't know that I had a modal pop up in the template. So I downloaded JCE.
I also disabled this funcion and nothing It's continue to open a page without menu and other staff of the page.
And if I search on Bing wiht keyword my page between the serp appear some page with ends ?tmpl=component

Any suggest if I can I block all index with ends ?tmpl=component ?

I notice that also joomlaplates website did it adding ?tmpl=component at the end of the url

Perhaps the biggest misunderstanding is that ?tmpl=component is always used to display a copy of existing content. But that is not the case it's also used to display unique content. Just examples: Articles that have no menu item linked or that are no called via a blog layout.
Many extensions are using it to display details of a topic or pictues that don't appear anywhere else on the site.

The best idea would be to post that on joomla.org, but somehow that is the concept of Joomla and has nothing todo with the theme itself

Anyway you can try this and add it to your robot.txt

Disallow: /?tmpl=component&type=raw

yes but in my case on the link it's just added ?tmpl=component

Do I have to insert in my robot text that?
Disallow: /?tmpl=component&type=raw

Thank you

Add this code

Disallow: /?tmpl=component&type=raw
Disallow: /?tmpl=component
