Error 500 at Admin-Panel after Upgrade to 2.8
Got the same problem. I did an automatic upgrade and now just got an error 500 warning message.
Then let’s hope there’s a solution for it. Don’t want to do the whole work to downgrade…
Rename your plugins folder to plugins2… then try again. I had the same problem today.
Ok, that worked.
Now I have the problem, that the ng-gallery doesn’t work. In detail it works but when I activate it I can’t access the admin-panel.
See if there is an update for your plugin or install it anew, however, it may simply just not be compatible with 2.8
fredparis11 Try temporarily renaming your .htaccess file. This is a hidden file so you will need hidden files enabled to see it. Also try increasing your memory_limit. There are different ways of doing that:
1. Increase the memory limit setting in php.ini (e.g. memory_limit = 64M ;). Many hosts may not allow this.
2. Increase the memory limit via .htaccess (e.g. php_value memory_limit 64M). Many hosts may not allow this.
3. Increase the memory limit via wp-config.php (e.g. define(‘WP_MEMORY_LIMIT’, ’64MB’);)
I am having the same issue 500 – internal server error.
Tried to auto update from 2.7.1 to 2.8 everything seems to go fine except for logging into the admin interface gives me an error. .maintenance file was not deleted after upgrade or the upgrade folder. Disabled all plugins renamed the directory and changed memory limits and nothing has worked.
Please let me know if you have any suggestions.
I am having the same issue 500 – internal server error when I try to access the admin interface. This is a new WordPress 2.8 installation on a own Win2008 testserver.
The Server has this setup:
Windows Server 2008 32-bit
WordPress 2.7.1 have no problem running on this server.
I have try to do a automatic upgrade from 2.7.1 to 2.8.
I get the following error when I try.
“Downloading update from http://wordpress.org/wordpress-2.8.zip
Download failed.: Operation timed out after 30000 milliseconds with 665760 bytes received
WordPress are running OK, but when we can’t get into the blog so we we have a problem Houston.
I got some keys on the French forum to resolve the problem (deleting files except wp-content folder and wp-config.php file, re-downloading 2.8 manually via ftp). The thing is it seemed to work (admin panel displayed) but my site remains as a blank page. I reinstalled my theme (blend) but I couldn’t activate it.
I chose to deleting 2.8 and reinstall 2.7.1. I reinstalled my theme and tried to activate it again:
Fatal error: Call to undefined function: automatic_feed_links() in /homez.154/unlivres/www/wp-content/themes/default/functions.php on line 9
I don’t understand PHP at all, I cannot fix this kind of bug. I decided to delete my content, reinstall 2.7.1, and recreate all my posts (fortunately, I started this blog June, 1st).
People, you can be sure I won’t upgrade WP until we get a truly robust and easy to use version, even for newbies like me.
The solution is to upgrade php to 5.3 http://ruslany.net/2009/06/upgrade-to-wordpress-2-8-and-php-5-3-on-iis-7/
Upgrade to 5.3 may not always help. There is a know bug in WP 2.8 that causes it to fail when logging on to admin page.
It has been fixed in 2.8.1.
Google Analytics by Denis de Bernardy made my admin fail. i renamed the folder in wpcontent/plugins and then the admin interface worked.
If not able to get to admin panel or even main page won’t load after automatic upgrade to WP 2.8, there is a very high change this behavior is caused by a plugin which was enabled at the time of the upgrade, but is not compatible with WP 2.8 code.
I’ve wrote a guide how you can identify the troublemaker here:
