Hi,
I've runned clients website at my hosting and everything was allright. Moved to clients hosting (files, database), I've seted everything up, main page is working, other links not (error 500) and I can't log into admin (you can try, "admin" "123" - I've got an empty page).
Hosting support gave me a log (below) and told me, that it's stupid wordpress and it never worked at their site. My client paid a small fortune for that stupid hosting (because "I'm here so long" and don't want to move) - could you advise me something?

takže samozřejmě je tam nějaký projekt se zacyklením těch rewrite rules.
