when i use page alias (index.php?id=##) [##=number]
the forum/helpdesk stops working.
as i need to enter
Frontend URL base: index.php?id=68
which gets transformed to index.php/68/ which sends me straigt to index page.

i got another page running, where i do not use the id's and use the links with html
i use exactly the same settings on this page, and set
Frontend URL base: index.php/Forum

at this page everything works fine!
you could now say... ok, then change your page alias, but fact is that the page is pretty large and i would need to check ALL links and change them from ?id=## to the page aliases...

any ideas?
