Thank you that was the problem but in reverse. In the Zoo filter module parameters I already had "Result Page ItemId" option to 154, I removed that and now it is working just fine.

the search is searching through client information so it is not open to the public, would you like me to email you the user & pass?

Thank you for the reply, i tried it and it works for the first search but when I run a search the 2nd time (from the outputted page) I get the following error...

Renderer Layout "item.frontpage" not found. (File: administrator/components/com_zoo/classes/renderer/item.php, Line: 45)
Renderer Layout "item.frontpage" not found. (File: administrator/components/com_zoo/classes/renderer/item.php, Line: 45)

It doesn't make sence because the is the URL output with the settings you suggested (doesn't work):
index.php?option=com_zoo&controller=zoofilter&task=dosearch&search_id=356&app_id=1&Itemid=119

Here is the URL output the ZOO sef turned off (does work):
index.php?option=com_zoo&controller=zoofilter&task=dosearch&search_id=358&app_id=1&Itemid=154

I am also using the following software
* Joomla 2.5
* PHP Version 5.2.17
* Joomla! 2.5.9 Stable
* JoomSEF Version: 4.4.0

After more testing (I cleared all urls & cache etc) I notice it works when I do a search from a standard page like the home page but not from the module search results generated page.

Non SEF URL from homepage:
index.php?option=com_zoo&controller=zoofilter&task=dosearch&search_id=312&app_id=1&Itemid=154

Non SEF URL from ZOOfilter results page
index.php?option=com_zoo&controller=zoofilter&task=dosearch&search_id=314&app_id=1&Itemid=154

I have noticed no matter what you search for the URL doesn't change

I am using Zoolansers 'ZOOfilter' and when I use the search function the SEF breaks the results

Here is the url output when searching for 'house' using the ZOOfilter
index.php?option=com_zoo&controller=zoofilter&task=dosearch&search_id=302&app_id=1&Itemid=154

Here is the url output after JoomSEF is turned on
portfolio/client-information/dosearch/zoofilter?task=dosearch&controller=zoofilter&app_id=1

Is there a way to turn off the SEF for modules or output?

was there ever a solution to this problem?
