AdsManager problem! If the URL contains a (.), Google handles 404 pages (otherwise come under the browser). What could be the solution? S.OS.

Helllo,

generally a dot (.) character in URL can cause a problem. This is related to webserver configuration.
My recommendation would be telling JoomSEF to convert "." charaters to a replacement character - e.g. "-" or leaving it out of SEF URLs completely.
This can be done in JoomSEF global configuration.
