 * Yesterday I uploaded the 3.5.2 update and now the site is corrupted. I takes 
   several attempts to get to a page and accessing my admin panel is not possible
   at all. The error message always change but starts with this everytime:
 * Fatal error: Call to undefined function wp_remote_post()…
 * The update seemed to failed at first so maybe it corrupted a file somewhere… 
   Where should I start to get this to work properly again?
 * Thanks everyone

 * 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 by FTP or PhpMyAdmin. Sometimes, an apparently
   inactive plugin can still cause problems.
 * – re-uploading all files & folders – except the wp-content folder – from a fresh
   download of WordPress.

 * How do I deactivate all plugins if I cannot access the admin dashboard?
 * I tried re-uploading all files and folders but the error keeps coming back as
   soon as I tried to access my dashboard 🙁
 * so should I tried coming back to 3.5.1 ?

 * Using ftp or the file manager at your host, rename the plugins folder plugins-
   old.

 * The same method to use the default theme. Rename your theme, theme-old and then
   wp will open with the default theme.

 * the error changed… but now all my blog is down and the dashboard doesnt look 
   good either. I did the plugin-old, oxygen-old (my theme)… here is my blog adress:
 * [http://www.monocommemoi.com](http://www.monocommemoi.com)
 * and the new error says:
 * Warning: require(./wp-blog-header.php) [function.require]: failed to open stream:

 * Looks like your installation is not complete. For example this mostly loads.

 * But this doesn’t and should.

 * Try downloading thw WordPress 3.5.2 zip file and then manually re-uploading everything
   in it except the `wp-content` directory.

   wp-content directory? and what do I need in the old database?
 * thank you
