I had the same problem on VBCShafter.com. I use GoDaddy to host my site and easily used the provided GoDaddy FTP web based program in the control panel to rename the directory (thus turning it off).
If you know who to use an FTP program like filezilla then you should be able to fix the problem in a few minutes. For you guys who don’t know how to, I’m sorry as you may need to get outside help on this.
Birgit S. Kern has a post above that looks promising. I’ve never tried that method, but I’m going to take a look at it.
I downloaded and then uploaded and older version 1.5.2.2 @: https://www.ads-software.com/plugins/simple-mail-address-encoder/developers/
