I got two separate wordpress instalation
http://www.kapler.cz
http://www.kapler.cz/tibetska-doga
when I run permalinks only on the first one, it works fine, but when i turn permalinks on also on the second one, it "jumps" to the 404 page (with right path e.g. http://www.kapler.cz/tibetska-doga/my-article-name
but with layout (template, header..) of the first instalation.
I have just did reinsatalation of the second blog to 2.1 (the first one is 2.0.6, and i am quite sure (but not 100%), that prior this reinstalation the permalinks were working normaly. I tried to delete both .htaccess and make permalinks live again, but nuthing helps.
Any idea?
