 * Hi there,
    I have a problem with the plugin, I developed my website locally with
   MAMP (PHP 5.4) and it worked perfectly, however, when I migrated it to the server(
   hostgator), I got the error saying it requires PHP 5.3 (it had 5.2), so I activated
   5.3 and now, when I click “Activate” I get redirected to a 404 error page. I 
   am using a custom theme but I have also tried to use the default ones (twenty
   twelve) with no success. I have also checked for the mcrypt library and it is
   enabled on my host. Any ideas on how to resolve this?
 * PS. when I revert to PHP 5.2 I do get the checklist of requirements and all of
   them appear correct except for PHP version.
 * Thank you very much!

 * Oh, I also tried to disable all other plugins and then activate and didn’t work
   either.
