Hi iamay,
You can manually disable the problematic plugin by using either an FTP program or your web hosts file manager. Rename the wp-e-commerce plugin to anything you like (wp-e-commerce_bk is an easy to identify one). This will at least bring your wp-admin area back up.
You may need to increase your memory limit for PHP. With most hosts, this is done through your php.ini file. If your web host uses the php.ini file (suPHP) you can follow these instructions: Update Local PHP Settings
If your host does’t run PHP as SuPHP, you will want to contact them regarding setting and updating your site’s PHP settings.
Hope this helps!
rename the /wp-e-commerce folder to deactivate it and log in
then explore these memory options
1. Try adding this line to your wp-config.php file:
Increasing memory allocated to PHP
define('WP_MEMORY_LIMIT', '128M');
2. If you have access to your PHP.ini file, change the line in PHP.ini
If your line shows 32M try 128M:
memory_limit = 128M ; Maximum amount of memory a script may consume (128MB)
3. If you don’t have access to PHP.ini try adding this to an .htaccess file:
php_value memory_limit 128M
Talk to your host.
