Creator of this plugin is not responding and i have no clue what is going on. BUT!
This plugin should be removed or marked as very dangerous because it will mess up your wordpress. I was not able to unistall wp-optimize because it contains wp-optimize inside url when clicking deactivate and then i get blank page as well.
So i deleted the plugin from ftp and this have removed wp-plugin from my wordpress but wp-optimize inside url is still going to blank page.
Like i say that i have contacted my host and they told me this:
The URL appears to be resolving to a blank page due a configuration with the scripting of your files. This is not a server side issue that is causing this.
So please help me out ehre, what did wp-optimize mess? Where in wordpress you can make some words when used in url to go to blank page?
Is this some kind of filter words?
