 * Hi,
 * I’m using Duplicator to create a carbon copy of a website I’m taking over from
   another designer who is stopping his business.
 * I’ve created the duplicator copy and tried to install it on my server but I received
   an error.
   You can find the error below (I’ve made some changes in italic for 
   privacy reasons.)
 * **Fatal error on WordPress login tests!**

 * What could be the problem with this?
 * Kind regards,
   Sander
