 * I was trying to upgrade to 2.0 and at first I got this error message:
    Warning:
   main(/homepages/25/d112340083/htdocs/blog_dir/wp-content/advanced-cache.php):
   failed to open stream: No such file or directory in /homepages/25/d112340083/
   htdocs/blog_dir/wp-settings.php on line 66
 * Fatal error: main(): Failed opening required ‘/homepages/25/d112340083/htdocs/
   blog_dir/wp-content/advanced-cache.php’ (include_path=’.:/usr/local/lib/php’)
   in /homepages/25/d112340083/htdocs/blog_dir/wp-settings.php on line 66
 * (It may have been WP Cache)then I tried deleting all the changed files and then
   uploading instead of replacing and then tried upgrading again and got this error:
 * Warning: main(/homepages/25/d112340083/htdocs/blog_dir/wp-includes/cache.php):
   failed to open stream: No such file or directory in /homepages/25/d112340083/
   htdocs/blog_dir/wp-settings.php on line 105
 * Fatal error: main(): Failed opening required ‘/homepages/25/d112340083/htdocs/

   25/d112340083/htdocs/blog_dir/wp-settings.php on line 105
 * After that I got :
 * Warning: main(/homepages/25/d112340083/htdocs/blog_dir/wp-includes/cache.php):
   failed to open stream: No such file or directory in /homepages/25/d112340083/

   What is going on ? And why can’t I upgrade ? If it’s some plug-in or something
   like that is there a way to start with fresh files but keep the post (database)
   Thanks.

 * I’ll say it before anyone else can
 * Right now you do not upgrade to 2.0, it’s a beta which means shit can and will
   go wrong… I just hope you backed up your database before you “upgraded” otherwise
   it’s very likely you’ll have tears before bedtime

 * I did it think but, see the problem caused me not to get any place other then
   typing in wp-admin/upgrade there was not database changing. I just was trying
   it out and this problem was partly just to tell you that there was a problem 
   and so for the stable version it would not there. But is it possible to delete
   all the files and still upgrade to lets say a clean version of 1.5.2 or what 
   files to I need to keep to do the upgrade… Thanks…
