Error 500 when goto admin panel after 2.8 failed update

Try re-running wp-admin/upgrade.php. If that fails, download a copy of WP2.8 and upload just the wp-admin & wp-includes folders plus the files in the WP root. Then try wp-admin/upgrade.php again.

When I run wp-admin/upgrade.php it says the database has been updated already. I just noticed that the files also have been upgraded, the modified data changed as i can see within my ftp program.

I have downloaded 2.8 manually now but I’m affraid i will damage the site too much if I overwrite all files with the already updated database. Is this really the way to go?

I just disabled friendly http messages in my internet browser settings.

Here’s the exact error message:

PHP Warning: file_exists() [function.file-exists]: open_basedir restriction in effect. File(D:\www\m\s\u\msuc.nl\public_html/wp-content/plugins/edit-tags.php?taxonomy=post_tag) is not within the allowed path(s): (D:\www\;c:\php5\pear;c:\windows\temp;) in D:\www\m\s\u\msuc.nl\public_html\wp-admin\menu-header.php on line 118

I just had the same message when I added a Viper Video plug-in. I can’t get into the admin page and would love to know what is the problem and how to solve it.

For all your convenience:

Here’s whats at line 118 inside the menu-header.php file:

if ( ( file_exists(WP_PLUGIN_DIR . "/{$sub_item[2]}") && ('index.php' != $sub_item[2]) ) || ! empty($menu_hook) ) {
					// If admin.php is the current page or if the parent exists as a file in the plugins or admin dir
					$parent_exists = (!$admin_is_parent && file_exists(WP_PLUGIN_DIR . "/{$item[2]}") && !is_dir(WP_PLUGIN_DIR . "/{$item[2]}") ) || file_exists($item[2]);
					if ( $parent_exists )
						echo "<li$class><a href='{$item[2]}?page={$sub_item[2]}'$class$tabindex>{$sub_item[0]}</a></li>";
					elseif ( 'admin.php' == $pagenow || !$parent_exists )
						echo "<li$class><a href='admin.php?page={$sub_item[2]}'$class$tabindex>{$sub_item[0]}</a></li>";
					else
						echo "<li$class><a href='{$item[2]}?page={$sub_item[2]}'$class$tabindex>{$sub_item[0]}</a></li>";
				} else {
					echo "<li$class><a href='{$sub_item[2]}'$class$tabindex>{$sub_item[0]}</a></li>";
				}
			}
			echo "</ul></div>";
		}
		echo "</li>";
	}

FTP into your wp-content/plugins directory and rename the individual plugin folders. And any lone scripts within wp-content/plugins. That will deactivate all of your current plugins in case one of them is causing this problem.

Hi esmi,

I just renamed 3 folders and 2 files with a .old extension. Thats all I had in the plugin folder. Still the same message which to me implies this is not a plugin problem?

I just renamed all of my plug-in folders also and it didn’t change the message

If you are hosted through GoDaddy, they are having some issues with their server. They said the issues should be resolved in the next hour or so.

Thanks for all of the other ideas

I’m not hosted through GoDaddy, there’s a lot of posts around already with the same sort of problems so its something within the 2.8 version upgrade that is not good.

I upgraded yesterday evening. Since I got 2.8 installed on the second attempt, I have regularly had Error 500 Internal Server Error messages when I try to move around the wp-admin area, or log into it.

I followed the installation instructions (long method) to the letter when I installed, so it is not something that I have done wrong. It can’t be the server because I did not get this message until I installed 2.8. I have disabled and renamed all the plugins, to no avail.

I am aware that others have been having similar problems. Unfortunately, I don’t have a solution but hope to figure one out in the near future, or I’ll be forced to go back to 2.7.1 as the current install is unworkable.

I’ve carried out 3 upgrades today without so much as a hiccup. Looking back at your error message, I’m wondering ifs this is a server config issue. Where are you hosted? Have you spoken your hosting provider?

No that renaming your folders does not affect the installed plugins.

Try moving (renaming) the plugin folders OUT of the plugins directory. For example:
cd to plugins
create a subdir named temp
move all plugins there temporarily

reload the wp-admin page.

I’m having the exact same issue:

PHP Warning: file_exists() [function.file-exists]: open_basedir restriction in effect. File(E:\Domains\sungjwoo.com\wwwroot/wp-content/plugins/edit-tags.php?taxonomy=post_tag) is not within the allowed path(s): (E:\Domains\madfellas.com\wwwroot\test;E:\DOMAINS\;c:\php5\uploadtemp;C:\PHP5\pear;C:\WINDOWS\TEMP;c:\php5\sessiondata;C:\Program Files\ImageMagick-6.4.2-Q16\;E:\Domains\sungjwoo.com\wwwroot/wp-content/plugins/) in E:\Domains\sungjwoo.com\wwwroot\wp-admin\menu-header.php on line 118

Any answers?

When I upload the version 2.7.1 wp-admin original files back to my website the admin panel is party functional again. Some parts still dont work good but at least for my website visitors the problem isnt visible at that moment for as far as i can see.

Still I dont want to be using older version php files, i want to be up-to-date. Any help would be geat.
