Thanks for the help Jason.
After I changed the menu position in the page and tested it I found the page would not open. Just a lot of text appears. It was OK ealier today.
I went to services and I found XAMMP Service is not running although set on automatic. I tried to restart but it come up with the message
The XAMMP service on the local computer started and then stopped.
I notice that if I type localhost in a browser I get to localhost/xammp correctly and if I click Status I see
SMTP service is Deactivated
FTP service is Deactivated
Tomcat service is Deactivated
All other are activated
I did check and my ftp software Core FTP seems to be running.
Any ideas are very welcome.
