WP installation – error

Hello,

i’ve installed latest version of wp on my hosted webspace. After surfing to the wp URL, i’ll get an error message “Internal Server Error” …

Error logs:
[Tue Nov 27 09:54:55 2007] [error] ALERT – canary mismatch on efree() –
heap overflow detected (attacker ‘8x.x9.x4x.xx’, file
‘/home/.sites/407/site520/web/demoei/wp-includes/taxonomy.php’, line 13)

The wp-config is configured correctly.

Thanks!
