website not displaying

Thanks for the suggestion but it did not help.The page was displayed in black and white (in firefox)with no design effect from css. in chrome nothing at all except the usual "This web page has a redirect loop. ERR_TOO_MANY_REDIRECTS"

Give all data about your web please:

• Operative system
  
• Web server
  
• Virtual host
  
• Project path
  
• Project Folders/files tree...
  

Greetings.
