I installed WordPress few days ago and now upgraded it to 1.5.1.3 (from 1.5.1.2). I followed the instructions (at least I believe so) but in the end my blog showed only a blank page. After experimenting with chmod (tried 666 and 777 for files and directories) I got a couple of php errors:
Warning: main(/home/int2000/14061/html/blogi/wp-includes/wp-db.php): failed to open stream: Permission denied in /home/int2000/14061/html/blogi/wp-settings.php on line 39
Fatal error: main(): Failed opening required '/home/int2000/14061/html/blogi/wp-includes/wp-db.php' (include_path='.:/usr/lib/php') in /home/int2000/14061/html/blogi/wp-settings.php on line 39
I'm not too familiar with php so I was not sure what that means. Has it something to do with the database?
Also, in wp-admin Presentation > Themes did not show any themes. Please see the screen capture: http://www.domnik.net/u/niko/wp-themes.png
Now, I cannot even access the wp-admin since it returns "403 Forbidden" error (probably due my chmod experiments?).
I'd greatly appreciate any help.
