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.
PHP is 5.3.13. [edit according to the host. The Open Hook plugin says it is 5.2.17]
Did it go away with Zend being added?
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)" 22.214.171.124 - -
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.
