Hello. I have a site based on SJ Live template from SmartAddons with built-in Adsmanager 2.9.11 in quickstart.

The problem is that server doesnt response 404 error when I type incorrect URL.

For example I have correct URL:
domen.com/index.php/ads-manager/content-...ic/69-lase-mapi-poza

Then I delete some symbols from this URL, for example:
domen.com/index.php/ads-manager/content-...s/3-civic/69-lase-ma
but in browser I see the same page. There is no 404 error. I clean site cash, I clean browser cash - nothing happens.

Then I delete more sybmols from this URL, for example:
domen.com/index.php/ads-manager/content-details/3-civ
but in browser opens a page with ads which if List of category Civic. There is no 404 error.

Then I delete more sybmols from this URL, for example:
domen.com/index.php/ads-manager/conte
but in browser opens a page ALL ADS. There is no 404 error.

Then I delete more sybmols from this URL, for example:
domen.com/index.php/ads-ma
but in browser opens a MAIN PAGE. There is no 404 error.

Only if I tape such abrakadabra in URL like this:
domen.com/abrarbarbarbarabrabr then 404 error is present.

What is the hell is this? Why there is no 404 error for incorrect URLs? Is this a problem of Adsmanager or it is a template problem?

Thanks in advance!
