Viewing a wordpress blog and seeing a perfectly blank screen is very worrying. Thankfully, there are a few quick things, that can often solve it.
- Disable Plugins. If you can’t login, just rename the plugin folder to (old-plugin2). If that fixes it, you can try reactiving individual plugins and see which one causes problem
- Add Memory. To wp-config add: define(‘WP_MEMORY_LIMIT’, ’64M’);
- Try Default Theme.
