Joomla 1.5 installation error !!
When i click on install sample data i get this error:
Error: the XML response that was returned from the server is invalid.
The issue was that in my php.ini file, i had: ‘display_errors = On’ – this showed up in the initial check screen as an issue, but i ignored it as i’m very experienced with Joomla! and never had a problem with this previously.
When i turned it to: ‘display_errors = Off’ – and restarted my LAMPP server to pickup the php.ini changes… worked. Turn it on… kicks the error! Most retail hosting servers have this off, thus the reason it works on those hosts.
HOPE THIS HELPS!
