Help solve the problem

Hi,
Which YOOtheme template do you use?
Try changing the setting for "Set page base href value" option in JoomSEF's Configuration on the Advanced tab.

YOOtheme template Cloud and Quantum.
Tried in the Advanced tab "Set page base href value"
Yes - always use only base URL
Yes - always use full SEO URL
NO - disable base href generation
No - leave original
on all four search option does not work :-(

Try also disabling the "Fix index.php links" option in JoomSEF's Configuration on the Advanced tab.
If that doesn't help, please post a link to your website so I can check the problem. Thank you.

The site usually DEMO (looking for a reason not working search)
installed:
1. DEMO site template Cloud
2. ARTIO JoomSEF 4.2.9

I think I've found a problem in JoomSEF. But because the Yootheme template is paid and I don't have access to it, could you send me your FTP access credentials to Tato emailová adresa je chráněna před spamboty, abyste ji viděli, povolte JavaScript so I could test if I can fix it on your website?
