 * I cannot install the plugin with WordPress version 4.5.
    Upon activation I’m 
   redirected to a 504 page.
 * Any clue?

 * Hello,
 * as i read the issue i immediately installed 4.5 on two test servers, but couldn’t
   reproduce.
 * The reason seems to be response delay between two servers in special
    server 
   constellation: [http://pcsupport.about.com/od/findbyerrormessage/a/504error.htm](http://pcsupport.about.com/od/findbyerrormessage/a/504error.htm)
 * I am sorry, i don’t know in the moment how to adapt my plugin for this server
   constellation case.
 * Best regards
 * Wasiliy

 * Thanks for the prompt reply Wasiliy, after a nasty database error connection 
   the issue solved itself and I was finally able to install the plugin.
    Marked
   it as solved!
