Cataloger pagination problem

[mauri]

Hi, all.
I have a problem with the catalog items pagination.

Versions:
- CMS: 1.3.1 - "havana"
- Cataloger: 0.7
- on linux host
- PHP: 4.4.7

Status:
I have several products (item pages) (sure, more than 200) divided  in several categories (category pages)
Each category show 10 items per page... So I have
- page 1 with items from 0 to 9;
- page 2 with items from 10 to 19
and so on...
To switch from a page to an other page (of the same category), I use the standard navigation mecanism offered in Cataloger templates... : so, I have some link like this...
http://mySite/index.php?page=myPage&start=0 to go back to page 1,
http://mySite/index.php?page=myPage&start=10 to go to page 2
and so on...

Problem:
I need click at least 2 times to really switch to the desired page.
Is not a problem of click on the correct link: the url in the browser address bar change correctly, but the content of the page don't change.

I'have tried checking the checkbox "Flush category page buffers" in section
"Extensions > Cataloger > Manage Preferences > Category Page Settings"
but the problem remains and more appears the message

"Warning: Cannot modify header information -
headers already sent by (output started at MyHost\modules\Cataloger\action.defaultcategory.php:8 ) in MyHost\index.php on line 289"

Anyone have an idea?

Thanks
mauri

Maybe the page it's on needs to have cache set as not cached?...

Maybe the page it's on needs to have cache set as not cached?...

for pages of type "category" (or catalog item...) , i don't have the options "Cachable" like in other types of pages

Have you flushed it and then cleared site cache?...

Have you flushed it and then cleared site cache?...

I have checked the flag "Flush category page buffers" in  Extension > Cataloger > Manage Preferences > Category page setting and the result is :

Warning: Cannot modify header information - headers already sent by (output started at /web/htdocs/www.mysite.com/home/modules/Cataloger/a ... gory.php:8) in /web/htdocs/www. mysite.com/home/index.php on line 289

when I browse a category
