WordPress 3.0 Install Problems

The stickied solutions are not working!!

This is my problem: First, I tried to install a plugin that didn’t work so I deleted it after I got the 500 Internal Server Error. That brought my site back. I emptied all of my plugins and decided it was time to upgrade to 3.0 while I’m in the process of updating my website. Well, when I try to auto-install, WP hangs on the downloading the .zip file and does nothing. There is a 0KB temp file created in my wp-config folder, but nothing progresses beyond the downloading dialog. It doesn’t matter how long I wait—I went to a production meeting and came back and it was still stuck there. So, I searched for help on the interwebs.

I have tried all the solutions.

I disabled plug-ins. I changed my wp-config.php file to up the limit from 32M to 64M (I don’t have access to my php.ini and I didn’t see a .htaccess even after I turned on hidden files). I went from 64M to 256M. I even tried a manual install but I wanted to make sure I didn’t miss anything by doing an automatic install over that. It went into maintenance mode. I had to delete the .maintenance file. Now, it’s back to hanging on the .zip file when I try to auto-install.

The Memory Bump plugin does nothing for me, even if its the only plugin left on.

I don’t understand the problem and I’m very frustrated. The manual upgrade appears to have “worked,” but I don’t think I’m seeing the new dashboard at all. I don’t think 3.0 is fully functional on my system.

My host is 1and1.com and I have contacted them.

Is there anything else I can do while I wait? ??
