Pagination over method parameters not working

Hello CI Community,
i am having problem for the pagination over method parameters.
My routes:

PHP Code:

$route['tag/(:any)'] = 'tag/index/$1'; 


The pagination works just perfect until i press the next page link!

PHP Code:

$pager['base_url'] = '/tag/'.$tagDetail->slug; 


this is how i have setup the base url in my tag controller index method but the problem is when i visit the index  method with a parameter then it shows "404 Page Not Found" if you want you can take a look at the production site here > Free People Photo now at the bottom from the pager click on the next page then it shows 404 exception, any idea for this situation?

Edit:
If i add the method name in the pagination's base_url like this

PHP Code:

$pager['base_url'] = '/tag/index/'.$tagDetail->slug.'/'; 


then the limit query override the limit with the tag slug! Look at the last part of the query:

Code:

... ORDER BY p.date DESC LIMIT people,20

in this query the limit has been replaced by the parameter of the index method of the tag controller! I need help...

Have a great day.

well you said that your pagination is working, but its not (pagination link's on supplied page are throwing 404 error). Post your controller code here so others can take a look and help, im a noob when it comes to routes..

The below part of documentation may help you fix this issue :

Then, Did you initialize the pagination with $config["uri_segment"] = 3; parameter? (change the segment number according to the url)

@karthik_code Thanks for your reply. Here is my pagination setup:

PHP Code:

//$pager['base_url'] = '/tag/index/'.$tagDetail->slug.'/';
        $pager['base_url'] = '/tag/'.$tagDetail->slug.'/';
        $pager['total_rows'] = 200;
        $pager['per_page'] = 20;
        $pager['uri_segment'] = 3;
        $pager['page_query_string'] = TRUE;
        $this->pagination->initialize($pager);
        $page = $this->uri->segment(3);
        /*
        if (empty($page))
        {
            $page = 0;
        }
        */ 


I have checked your website.
Pages with people tag throws 'No photo' message on page number 4 and above.
This is due to the following hard coded value in the above code.
$pager['total_rows'] = 200;

Dynamically count and set total rows like this.
$pager['total_rows'] = $this->photo_model->count_by_tag($slug);
(You may know this already because other pages programmed perfectly).

I have solved the problem using a custom hack... Thanks for mentioning counting total rows dynamically
