 * I have no idea what happened. I was not doing anything besides moving around 
   my admin panel when this error suddenly appeared on my site at the top of _all_
   pages.
 * strpos() [function.strpos]: Empty delimiter. in /home/spoken/public_html/wp-includes/
   compat.php on line 124
 * I searched the forums here for both strpos() and compat but found nothing to 
   help me out.
 * My site is spoken-for.org and as of now, the error is still there. I upgraded
   to 2.2.1 from 2.2 after getting this error, but it’s still there.
 * Line 124 of compat.php reads:
    return strpos(strtolower($haystack), strtolower(
   $needle), $offset); and is under the section “added in PHP 5.”
 * I have PHP version 4.4.4.
 * Thanks, everyone

 * Well… adding:
 * AddHandler application/x-httpd-php5 .php
 * To the top of my htaccess to make my site use PHP5 worked in getting rid of it
   and so far all my plugins seem to be okay…

 * And…. it’s back. I should be running the newest version of WordPress yet out 
   of the blue, here it is again. There’s an error at the top of my pages on the
   frontend that quickly gets hidden under the header image but this is what my 
   admin panel says, I can’t do anything in there whatsoever:
 *     ```
       Warning: strpos() [function.strpos]: Empty delimiter. in /home/spoken/public_html/wp-includes/compat.php on line 55
   
       Warning: Cannot modify header information - headers already sent by (output started at /home/spoken/public_html/wp-includes/compat.php:55) in /home/spoken/public_html/wp-includes/pluggable.php on line 694
       ```
   
 * Googling this and the first result is –da da da– this thread, followed by unrelated
   stuff.
 * The PHP5 call in my htaccess was still there but commented out with #. I DO NOT
   remember doing that, not sure why I would have done that. My server is now apparently
   running 4.4.8 of PHP. Trying to remove that line or uncommenting it, even, results
   in the site not being to load at all. Changing it to this:
 *     ```
       AddType application/x-httpd-php5 .php
       AddType application/x-httpd-php .php4
       ```
   
 * (which I found in the only other thread a search of these forums turned up) results
   in the site loading on the frontend but still with the error and still with the
   errors and unuseable backend.

 * Change this line:
    `return strpos(strtolower($haystack), strtolower($needle),
   $offset);`
 * To this:
    `return @strpos(strtolower($haystack), strtolower($needle), $offset);`
 * That will suppress the warning.

 * Thank you Otto42! As you can see, I only know enough PHP and WordPress to get
   myself into trouble. 😛
    That does suppress the warning and lets me back into
   my admin panel. I guess there’s no real issues here to worry about??
