OK, I have reinstalled gamma 2, VB 4.2.2. vbseo, set URL to "wiki" (was wiki_index) and url Path to /wiki/Prefix:Article.
Wiki main page and special pages are now accessible under a very nice url
Further I have a bug in AdminCP -> Usergroups -> Permission.
See attached Image.
I have set AdminCP -> VW -> Permissions of administrator to all Yes.
When I edit wiki index page:
1. The text is stored, but I am redirected to the edit form
2. Line Breaks are killed ("\r\n" => rn) (Pro Memoria: I use ISO encoding, not UTF)
3. when I create an area and edit its main page I am shown a edit success message and redirected to said area main page
Also I see no "Create new page link"
When I add a link in the index page and click it I get a "page not found". before reinstalling I got a vbulletin error no permissions.
thus ruling out rewrite rules as the problem.
Given last point I assume that linking a non existing article would lead me to creating it.
Also when I try to add a category before the layer pop up has time to come, the page is reloaded, thus not able to save categories.
When I edit main content and then add a category I can cancel the "do you want to leave page" JS alert, thus I can access the add category layer popup, but unfortunately the submit button is disabled...
PS: the button is only disabled after I press it. Its related to changing the url to /wiki/ instead of wiki_index.php. The url called is: domain/wiki?do=publish&itemtypeid=7
it should be:
domain/wiki/?do=publish&itemtypeid=7
this leads me to the question if wiki/ instead of wiki should be entered as "name of file or folder" (originally "wiki_index")
PS: also after the code replacement you have mentioned in your first post I don't think VW still works in default configuration using wiki_index.php as it actually points to wiki_index/
