You must be missing `wp-includes/http.php` and may be missing other ones as well. * Thread Starter [mavto](https://wordpress.org/support/users/mavto/) * (@mavto) * [17 years, 6 months ago](https://wordpress.org/support/topic/error-after-upgrading-2/#post-922607) * thanks a lot markjaquith, now is running quite fine * [Leo Caseiro](https://wordpress.org/support/users/leobok/) * (@leobok) * [17 years, 6 months ago](https://wordpress.org/support/topic/error-after-upgrading-2/#post-922727) * update only the file cron.php and will be successful. * [tjmapes](https://wordpress.org/support/users/tjmapes/) * (@tjmapes) * [17 years, 6 months ago](https://wordpress.org/support/topic/error-after-upgrading-2/#post-922825) * I’m getting the same error … I’m actually getting 2 errors, then after i refresh through those, the site comes up.

Please help or post a solution if you’ve had this issue and resolved it, thanks!!!! * [tjmapes](https://wordpress.org/support/users/tjmapes/) * (@tjmapes) * [17 years, 6 months ago](https://wordpress.org/support/topic/error-after-upgrading-2/#post-922913) * Got it figured out with the help of jford. * over on the wordpress 5 minute install page…. it tells you what files not to delete/overwrite.. well i tried this and it didn’t work.. * so i basically overwrote everything in there (making backups of my wp-content folder first) and once i had uploaded all the files for WP 2.7, then i uploaded plugins folder, activated them, i then i uploaded my theme. * works now 🙂 hope it works for the next person. Thanks again JFord * [joshroseman](https://wordpress.org/support/users/joshroseman/) * (@joshroseman) * [17 years, 6 months ago](https://wordpress.org/support/topic/error-after-upgrading-2/#post-922971) * **RESOLVED by myself:** I forgot to upload the root directory of WP. So please feel free to ignore my ignorance. I got so swept up in backing up the right stuff that I lost track of my steps. * ******************* * Fatal Error achieved: * `Fatal error: Call to undefined function wp_remote_request() in [godaddy.com hosting account]/html/wp-includes/update.php on line 58` * Occasionally, I also get the error in cron.php on line 201. * I did everything instructed: * 1. Delete wp-admin. 2. Delete wp-includes. 3. Back up wp-content. 4. Delete wp-content. 5. Upload wp-content. 6. Run upgrade. 7. Upgrade Database (WP’s upgrade system said I needed to, so I did). * That’s when I got the above fatal error. * I then tried to re-upload my plugins (all one of them) and themes (all one of them), and still achieved a fail. * Suggestions?
