SUBDOMAIN: Click an ad and it takes me to domain.tld/search

This is a fresh install.

I've successfully configured subdomain installation, but when I try to click the ad (the example ad from osclass, https :// sub . domain . tld / example-ad-i1) then it will always bring me to https :// sub . domain . tld / search

Looks like issue to recognize item URL.
Do you have same problem without subdomains?
Have you modified permalink structure?

I've emailed you the website url and the admin login information.

You may log in and investigate the problem yourself.

This is a new website so no security issue if i shared the admin login information to you.

Thank you.

Checked, some issue with permalink or htaccess, without subdomains works ok.
Tested on some of our installations and could not reproduce.

The content of  .htaccess file is already similar like osclass recomendation.

Yeah but there could be some other redirect, hard to identify, someone would need to spend few hours on it to identify where that redirect comes from.
