WP 2.7 Fatal Error Please Help

Hi there,
I tried to update from 2.6.5 to version 2.7… like so many others and I got a “Error 500: Script Execution Failure” on my screen. Never mind, I thought and tried to reinstall 2.6.5. CauseI read here, that I am not the only one with problems regarding 2.7.

Whenn I deleted everything, literaly everything, including my database, and wanted to start from scratch. “Error 500: Script Execution Failure” again with 2.6.5

My webhoster recomendet ASCII for uploading scripts via ftp so I deleted everything again and made sure it was uploaded with ASCII this time and I also checked for 755 permission. Still I receive the following message on my screen when I try to run install.php of WP 2.7

[www.malterautert.de] [Mon Dec 15 10:52:39 2008] [error] Premature end of script headers: install.php
Error 500: Script Execution Failure
Description: The server encountered an internal error or misconfiguration and was unable to complete your request.

Most common reasons for returning this error message are:

? File Upload Mode
When you upload Perl, CGI scripts via FTP you should use always ASCII mode. If you get "Error 500: Script Execution Failure" you should check whether your FTP client uses ASCII mode when uploading your scripts, because if it uses BINARY mode to upload your scripts they won't work on the server. The problem caused by wrong upload mode is associated with the way different operating systems handle the "end of line" character. Unix system uses a "line-feed" (LF), Windows uses a "carriage-return" (CR) and "line-feed" (LF) pair. That's why it is very important that you set the uploading mode to ASCII.

? File Permissions
When you upload scripts via FTP the file permissions are set by default to 755. If you get "Error 500: Script Execution Failure" you should check whether your scripts have 755 permissions. Otherwise your scripts have lower level of permissions and does not support execution upon request. The octal representation of the 755 permission is equal to the following textual format: -rwxr-xr-x
Most FTP clients support the CHMOD command which is used for setting file permissions. In case you have set improper permissions to your scripts, use your FTP client and set "Read, Write, Execute" permissions for the owner, "Read, Execute" permissions for the group and everyone else.

? Script Errors
This is the third well known reason for getting "Error 500: Script Execution Failure" upon execution of your scripts. Check your scripts for any obvious syntax or programming errors to make sure your code is not broken.

Remember: When you get a "Error 500: Script Execution Failure", you should always check for any file uploading problems (ASCII/BINARY) and the executable permission settings. Once those are checked and verified, it looks like there is a syntax error or some other problem in the script.

I don’t know what is wrong, cause before trying to update to 2.7 installation of 2.6.5 was no problem at all and now everything seems to be a mess.

Thanks for posting those instructions guys. What you said worked perfectly.

I can’t seem to get to the site admin or my blog.

both my blog site and my admin page get:

Fatal error: Call to undefined function: wp_remote_request() in /mnt/w0501/d30/s39/b01e3297/www/wordpress/wp-includes/update.php on line 58

I tried many of the above options, but nothing seems to work.

All the plugins are disabled, I used filezilla to upload 2.7. I used overwrite. I get the same fatal error. Any help is appreciated.

What worked for me:

Upload the 2.7 Zip file to your server

Un-archive or decompress it.

Delete the wp-content folder.

Move the files & folders to where you had your old wordpress files and overwrite them.

Visit: https://www.InsertYourSiteHere.com/wp-admin/

It may ask you to update your database.

And with one click (If you’ve gotta update your database), your outta the woods.

Hope this helps!

EDIT: It’d probably help if I told you the error I had:

“Fatal error: Call to undefined function: wp_remote_request() in /home/content/a/s/a/asantos24/html/wp-includes/update.php on line 58”

I came up with a few others as well, but the course of action above fixed ’em.

It is interesting that the only fix seems to be a manual install from a tarball. I have been using SVN forever to upgrade my WordPress, and doing the switch to tags/2.7 causes the same fatal error every one else is seeing. So I did an experiment. I deleted everything they say to delete or overwrite in a manual install, and did an svn up. Theoretically, that should have solved it. It did not. I am now going to try doing a full svn checkout and copy my config file and theme over.

Well, that worked. Something is not behaving properly in the svn switch.

I also had this problem, and what many of the people here are saying is correct: Deactivate the WP Auto upgrade plugin and you should have no troubles.

For the experts recommending uploading everything, the reason that so many people “Screw it up” is simply because often an FTP client will overwrite the entire WP-content folder, uploads, extra themes and all. It’s not the users fault – keep in mind many people aren’t all that familiar with FTP – WordPress’ upgrade page even says not to upload the whole thing because you can overwrite things.

I am new to blogging and wordpress 2.7, also using Thesis theme 1.5

I have no idea what I have done and as I don’t know code (html or css) I would appreciate help in the easiest terms possible.

Herewith error message on my site:

Call to undefined function wp_quotes_random() in /home1/cyberspi/public_html/wp-content/plugins/thesis-openhook/functions.php(228) : eval()’d code on line 2

Would some kind soul please help me.
Thank you
