first i had wp 1.5 (default theme with no changes) and all of the sudden everytime one wrote a comment and clicked to post it they got a blank "wp-comments-post.php" page.
I saw a newer version so i upgrated hoping it would fix it but it did not. I found other posts here that said either that the problem came just like in my case just like that but to those just like that it also went away. Others wich have modified the template were adviced to mind a change in the code and it worked for them but thei had earlyer versions with diffrend file names and I don't realy know that much coding but html and css so i could't tell if or how it would be in my case.
Please, if anyone can help out here, do so. My blog is like this for almost a month now. It is at: http://jurnal.adrianradic.com
