 * Hi all,
 * I’ve upgraded to 2.8.1 and I’m getting this error when trying to log in to admin:
 * Fatal error: Call to undefined function: _deep_replace() in /home/www/XXXXXXXXXXXX/
   blog/wp-includes/pluggable.php on line 884
 * I’ve searched the forums and have deactivated all plugins and removed blank characters
   and spaces at the beginning and end of my pluggable.php and wp-config.php files,
   but nothing has helped.
 * Can anyone help me?
 * Thanks in advance.

 * by the way, line 884 in pluggable_php says:
 * $location = _deep_replace($strip, $location);
 * thanks!

 * Getting the same error on a clean install of 2.8.1. I’ve tried replacing “_deep_replace…”
   with “deep_replace…” but that does not help. Is it possible our hosts are using
   an outdated version of PHP?

 * I had another look. There is, in fact, no _deep_replace() function inside pluggable.
   php. I’ll start trolling through some other likely suspects.

 * i’ve given up and downgraded to 2.7. i think i’ll wait until there’s a better
   version released…

 * Same issue with a clean install of 2.8.1 beta 1 when visiting the install page
   for the first time.

 * Also… no tables were created in the database before the fatal error if that gives
   a clue to the sequence.

 * You didn’t get a good install. Delete all the files and reupload them. Ideally,
   you should unzip the file on the server, rather than unzip on your computer and
   upload via ftp.

 * hallsofmontezuma,
    did just that – same error on clean install, unzipped on the
   server…

 * Commented Line 884 of pluggable.php – everything worked, tables created, installation
   hasslefree. No idea about the consequences, but will test and report…

 * Try 2.8.1 Beta 2 to see if this makes a difference. There was a change to this
   after beta 1.
