Problems with MediaWiki

Here are the problems I am having with my MediaWiki installation at http://wikademia.org/Main

Any help would be appreciated extrodinarily. Thank you.

I have listed the problem URL's, and below them a description of the problem.

====Scratch namespace====

http://wikademia.org/Scratch_talk:Astrophysical_Hydrodynamics

http://wikademia.org/Scratch_talk:Norrland

http://wikademia.org/Scratch_talk:Futures

http://wikademia.org/Scratch_talk:Härjedalen

http://wikademia.org/Scratch_talk:Atomic_Structure_and_Spectra

http://wikademia.org/Scratch_talk:Latice

For these pages, the actual redirect pages will show up when using the random feature, and should not do so.

====Broken page titles=====

http://wikademia.org/Spanish_1/Chapter_10_(Family_&_Celebrations)

http://wikademia.org/Spanish_1/Chapter_11_(Adjectives_&_In_a_restaurant)

The page titles are broken, and show up when using the Special:Random feature, unfortunately.

=====Mysteries=======
http://wikademia.org/index.php?title=C_Source_Codes&redirect=no

This redirect shows up occasionally when using the Special:Random feature, and it should not do so.

=====Page links in Special:Statistics=====
on http://wikademia.org/Special:Statistics - at the bottom - even if the customized user group pages are created, the links still show up as red.

=====Broken page and title=====
http://wikademia.org/Simple_math_in_C

This should read "Simple math in C++" - see: http://wikademia.org/Special:Search?search=Simple+math+in+C++&fulltext=Search




Thank you .
