Cannot replace an email address

I tried 2 different plugins for just replacing an email address and no one is working, including this one.

I’m trying to replace “[email protected]” with “[email protected]”.

Error:

“Your search contains your current site url. Replacing your site url will most likely cause your site to break. If you want to change the URL (and you know what you doing), please use the export function and make sure you backup your database before reimporting the changed SQL.”

Ok, dude. I’m not replacing my site URL. Just an email address.

After this, I’m trying a “trick” like replacing “info@mydomain” with “hello@mydomain” (it shouldn’t be as this, but doesn’t care).

Select ALL tables.

Deactivating “Dry run”.

Select “Save changes to Database”.

I enter on my widgets area and there is no changes applied to this query on the text widgets :-S
