 * Hi everyone, I have recently installed WP 2.0 on a new site. No upgrades, just
   a normal install. At the top of my page it says “Warning: Invalid argument supplied
   for foreach() in /home/waterblo/public_html/wp-includes/capabilities.php on line
   19” What does this mean? How can I fix it?
 * Thank you!
 * EDIT: It seems that I cant login to the admin section! This is the error I get,“
   Warning: Invalid argument supplied for foreach() in /home/waterblo/public_html/
   wp-includes/capabilities.php on line 19
 * Warning: Cannot modify header information – headers already sent by (output started
   at /home/waterblo/public_html/wp-includes/capabilities.php:19) in /home/waterblo/
   public_html/wp-includes/pluggable-functions.php on line 177″

 * You can try changing line 19 of capabilities.php to:
 * `
    foreach ((array)$this->roles as $role => $data) {
 * The interesting thing here is that I don’t have a prefix_user_roles table (on
   my 2.0 database), which is where this particular function reads data from??

 * Well, thanks for the help. I tried to fix it, but the error just jumps lines 
   on me. I think it has something to do with this:($this->roles as $role => $data)
   its on line 19, currently, its deleted from it (I took it out in an attempt to
   fix it). If anyone can help, thanks alot!!
 * EDIT: I didnt see all the posts everyone made, let me try those. If it doesn’t
   work, I’ll post back again.
 * 2nd EDIT: jaredquinn, THANKS! I got it to work now, the error is gone. A new 
   one has come up though! When I try to login to the admin page, it says I do not
   have sufficient permissions! I am logging in with the correct password to my 
   admin account. If anyone can help, triple thanks!

 * If you have a wp_user_roles table try renaming it to something else, I don’t 
   have one on my 2.0 install, yet the file you’re getting these errors in does 
   seem to query one (and gracefully exit if it doesn’t have one)

 * If you try the above you should backout the last thing I suggested too.

 * Where would this file be? I am currently loading a backup (yesterdays). If it
   doesn’t work, I’ll have to look for that file. Thanks for all the help, I really
   appreciate it.

 * Sorry it is (could be) a database table…

 * EDIT: I got it to work, thanks!
