Yesterday I installed WP without problems, I tried it out and it worked fine. However, I wanted it in another directory. So I deleted all files and all tables in the database. Then I did a new installation in a new directory. That seemed to be OK at first, except I got a blank page when I clicked on Themes in the Admin panel. Not knowing what was wrong, I deleted all files and the database tables once again, and tried a new installation again in the same directory. Now I get stuck during installation. Install.php lets me enter database name, password etc and it says "All right sparky!". But when I click the "Run the install"-button, I only get a blank page. And nothing more. If I try to open another php-file (such as index) I also get a blank page. When I check my database, I can see that no new tables have been created.
What is wrong???
