 * I used this brilliant plugin on my main domain: [http://purple-octopus.nl/](http://purple-octopus.nl/).
 * I used it to change the prefix into a random code. But now the 2 subdomains that
   I had on this domain don’t work anymore.
 * It’s not a matter of just waiting since the subdomains did function normally.
 * The error says tat it can’t find the server.
 * Is this because I need to change the subdomain prefix to the same as my main 
   domain or should this not be a problem?
