When I have HACK enable Host Menu links are not working an error page is generated. When HACK is unistalled "no problemo" host config pages are enabled.

Observation:
When you type URL manual default.aspx?tab=X&portalid=0 everything is OK
but when clicking link in menu default.aspx is disapiring (host)?tabid=X
language tag is also in wrong place in URL - at the begining

I am using DNN 5.4.1
Any ideas how to manage this url rewrite problem of DSLocalizator

When I turn off REPLACE URLs and REPLACE SOLPART LINKS (Querystring always enabled) there is no errors in getting to Host Menu links or this shortcut with default.aspx

I am using DNN in intranet. No connection to Internet.

There are my errors when both above mentioned option are on
1:
http:www.serwer.com/?tabid=40  (working but...no default.aspx before ?)
2:
when any host link is pressed url is looking "more or less" like this
http:www.serwer.com/language/en-us/default?tabid=40 (rest of url is OK) this gives an error and browser goes to error page set in web configuration file (CustomErrors line) of DNN. If you literally remember you can type correct URL to respective part of Host menu (ie. SQL) and you there. But who is....
