Could be a php memory issue. Remove the .maintenance file and use one of these methods for increasing the amount of memory a PHP script may consume
1. If you have access to your PHP.ini file, change the line in PHP.ini
If your line shows 32M try 64M:
memory_limit = 64M ; Maximum amount of memory a script may consume (64MB)
2. If you don’t have access to PHP.ini try adding this to an .htaccess file:
php_value memory_limit 64M
3. Try adding this line to your wp-config.php file:
define('WP_MEMORY_LIMIT', '64M');
4. Talk to your host.
The .htaccess solution and the wp-config doesnt fix it.
The WP3 Beta 2 worked out just fine on the earlier beta 2 releases, but the last update kind busted the feature. Tried to install on different fresh enviroments, but it stil doesnt work update automaticly.
Can you confirm its a single problem on my enviroment and the update runs all ok on your enviromen??
It runs, but it doesn’t run perfectly on ALL environment. It’s a known … hmm … inconvenience that the size of 3.0 is too much for some, smaller, shared hosts to handle and it can bork out.
If options 2 and 3 failed, try 1 or 4 🙂
