will it solve the problem if I overwrite the php file of another blog over my blog? I failed to make back ups (idiotic, I know). The php files along with the wp-* folders are more or less the same as the one in the downloaded zips, right?
I checked the past topics and no, I havent changed the code lately, nor am I using a the plugins talked about in the threads. I just made a post and the white screen appeared.
