My webhost updated his server (PHP 4.3.9 -> 5.1.6, MySQL 4.0 -> 4.1) with the result that my 2 wordpress blogs are dead.
Both blogs now just show a blank page. The error-log of the server has entries such as
File does not exist: home/httpd/vhosts/sirruf.net/httpdocs/kuibyshev/comments
sirruf.net is my domain and kuibyshev the dir one of my blogs was in.
According to my host, wordpress itself generates a segmentation fault but everything should be ok with PHP (my lifetype blog works) and SQL (database access works).
I tried a fresh install of wordpress in another directory and with a new, empty database but couldn't get to the second step of the installation. When clicking on 'continue to second step', either a blank page (with IE) or a prompt to download 'install.php' (with Firefox) appeared. The configuration of the db is ok.
Any ideas what I could do?
