 * Version: 3.6-alpha-23400
    Clicking on the add media button works as expected 
   but on the server this message is generated in my error log. `[12-Feb-2013 11:
   23:21] PHP Warning: Zend Optimizer for PHP 5.2.x cannot be found (expected at'/
   usr/local/Zend/lib/Optimizer-3.3.3/php-5.2.x/ZendOptimizer.so') - try reinstalling
   the Zend Optimizer in Unknown on line 0`
 * My host, Dot5, says
 * > I have added the zend_optimizer code for your account.

 * What version of PHP are you using? 5.2.what?
 * Did it go away with Zend being added?

 * PHP is 5.3.13. [edit according to the host. The Open Hook plugin says it is 5.2.17]

 *  No the message still gets written to a file called error_log in the wp-admin
   folder as soon as I click on the add media button. I was mistaken that was the
   server log. The server log for that same time (I think) says this.
    `[12/Feb/
   2013:00:23:35 -0500] "POST /wp-admin/admin-ajax.php HTTP/1.0" 200 295 "http://
   www.ourexcellentadventures.com/wp-admin/post.php?post=7830&action=edit" "Mozilla/
   5.0 (compatible; MSIE 10.0; Windows NT 6.1; WOW64; Trident/6.0)" 76.72.167.90--`
 * I had never noticed that file before but it was over 5MB with that same message
   going back to September 2012. There are also messages about a plugin I had that
   was not working. I put the .txt extension on it so I could read it.

 * Two VERY belated thoughts.
 * 1) The fact that you have plugins saying 5.2 and the host saying 5.3, I think
   PHP is the hissy fit here.
 * 2) Clean out your tmp folder on the server.
 * But I really think it’s something FUBAR in PHP :/
