Hi,
try to disable cache in search modules:
- go to Administration->Extensions->Modules
- search and open Search Module
- go to tab "Advanced"
- set parameter "Cache" to "no cache"

i send pic, all modules by default has that option disabled

I have just tried and works, but I need to report a problem, you have installed Basic version over the Pro, so you have a old plugin for ajax search that not works correctly. You should disable this from plugin manager, plugins is called "Easy Profile - Ajax Userlist". maybe the problem is here.

you rigth, remember that i was used an old version that my client supposedly was buyed, seems i was forgot to uninstall old plugins, gonna try and let you knows

Sorry, you have right, only read the last answer.

Problem:
you have a template override for the user list view, from version 2.x.x we recommend to delete all template overrides (http://docs.easy-profile.com/index.php/article/upgrade-1x-2x).

About user list, from version 1.x to version 2.x, basically we have changed the method to send parameter from a search form (1.x use POST and 2.x use GET).
This solve problem with browser back button.

Solution without delete all template overrides:
You can simply change form method from POST to GET:
- Open file at /templates/jp-hifi/html/com_jsn/list/table_search.php
- Replace this

method="post"

with this:

method="get"

That's it. Thank you for your support
