 * I just automatically upgraded my WP after a period of inactivity, and now when
   I try to update a page I get these two messages:
 * `Warning: is_writable() [function.is-writable]: open_basedir restriction in effect.
   File(/) is not within the allowed path(s): (/home/user123:/usr/lib/php:/usr/local/
   lib/php:/tmp) in /home/user123/public_html/blogfolder/wp-admin/includes/misc.
   php on line 128`
 * `Warning: Cannot modify header information - headers already sent by (output 
   started at /home/user123/public_html/blogfolder/wp-admin/includes/misc.php:128)
   in /home/user123/public_html/blogfolder/wp-includes/pluggable.php on line 865`
 * Neither impede the actual publication of my changes, but it’s very annoying having
   to re-navigate to the admin area manually each time. I’ve looked through many
   topics on the first error, and have followed every instruction I found, but none
   are successful. I’ve tried the official solution to the second error, but removing
   excess whitespace (or whatever the “delete button” method is for) didn’t work
   either. I figure the errors could be coming from the same place, or have similarities
   because they both involve the misc.php file.
 * Please don’t just refer me to a search query or previous topic, because I’ve 
   checked thoroughly through them and can’t find anything that works. I’m not the
   most tech-savy person around when it comes to PHP, so a little guidance would
   help immensely.
