Site blocked during using wp-optimize

I installed new version of the Wp-optimize yesterday and today I tried to clean up my site and while it was optimizing, I saw it took a long time and checking it I saw actually it is stocked while cleaning the database. So I got out of the WordPress dashboard and reboot the browser to get into the WordPress dashboard but I saw an error message saying “Error establishing a database connection”.

So then I tried to disable the plugin in our server, and it is still the same I receive the same error message …

Can you please help me out of this mess?

two months ago I had another problem with wp-optimize and that time by disabling the plugin in our serve I could open the site. But this time that solution dose not work.
