Good evening.
I've just upgraded to WPMU 2.9.1.1
Prior to upgrading all the blogs on my system were blank. After the upgrade they are still blank.
By "blank" I mean that only white appears when going to any blog address.
For instance: http://prodos.thinkertothinker.com
However, if I go to the admin address of a blog (..../wp-admin/) I can log in to the Dashboard without a problem.
If I go to ...
Posts >> Edit >> (choose a post) >> Click Edit
... I can see the content of the post.
If I try to view the post or to preview the post, I just get a blank white page.
After upgrading to 2.9.1.1 I tried to upgrade the 4 plugins that needed upgrading.
I used the automatic upgrade option.
In each case I got an error message like this:
Downloading update from http://downloads.wordpress.org/plugin/photopress.zip.
Unpacking the update.
Installing the latest version.
Deactivating the plugin.Warning: Cannot modify header information - headers already sent by (output started at /home/prodos/public_html/thinkertothinker.com/wp-admin/admin-header.php:18) in /home/prodos/public_html/thinkertothinker.com/wp-includes/pluggable.php on line 868
Removing the old version of the plugin.
Any thoughts on this problem would be greatly appreciated.
Thanks.
Best Wishes,
