   > The precondition on the request for the URL /prototype/wp-admin/media-upload.
   > php evaluated to false.
   > Additionally, a 404 Not Found error was encountered while trying to use an

 * I get the above error message whenever I try to insert an image into my page/
   post. Everything worked fine for months since until about 3 weeks ago. I’ve tried
   everything I could think of to no avail.
 * I have other sites running on 3.2.1 with no image upload/insertion issues.
 * Please help.

 * Have you tried:
 * – deactivating **all** plugins to see if this resolves the problem. If this works,
   re-activate the plugins one by one until you find the problematic plugin(s).
 * – switching to the Twenty Eleven theme to rule out any theme-specific problems.
 * – [resetting the plugins folder](http://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F)
   by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause
   problems.

 * Update:
    * I’ve tried deactivating all plugins but the problem’s still there –
   images upload/crunch fully until I click “insert into post”. 🙁
 * Going to try switching to the twenty eleven theme now.

 * Highly unlikely. This is specific to your site. Have to asked your hosts about
   this? It could be server config issue.

 * server configuration? but it used to work just fine!
 * anyways, are there any specific server configurations from the host that could
   affect WP in this way? I mean, if there’s anything specific I should ask about?

 * Sorry but that’s like asking how long is a piece of string. There are as many
   server configurations as there are servers. And it is not uncommon to find different
   config with the same host. The error message is server-related. It’s not coming
   from WordPress.

 * I’m currently experiencing the same problem with my hosting service. I am pretty
   certain that it’s a mod_security issue. I’ve vainly tried everything under the
   Sun to filter the file that exploits the precondition via my .htaccess file. 
   But I recently discovered that there’s nothing I can do myself to resolve the
   issue. Since v2.5, Mod_security no longer allows for disabling using one’s .htaccess—
   the httpd.conf must be edited. You need to contact your hosting service tech 
   support and request to have mod_security disabled (i.e., commented out and whitelisting
   the domain). I hope my hosting service tech support handles this soon! I’ll report
   back here and give an update.

 * Here’s that update. My host indeed disabled mod_security. I am now able to insert
   images into posts without encountering the HTTP error. I am curious to hear back
   from [@levelsevenltd](https://wordpress.org/support/users/levelsevenltd/) as 
   to the status of the original problem.

 * You seem to misunderstand. Instead of posting your questions on other pages [like this](http://wordpress.org/support/topic/wp-adminpostphppost328actionedit?replies=20#post-2936273),
   open your own topic so that you will get better attention.
