..and ended up with a website stating "Configuration error 23 - reset in 15 minutes"
I'll revisit things later (it's a test site so not critical) but I wonder what I did wrong, or if this is a fake message to deter people trying to break in. In any case, I may have to forego the "?<magic word>" parameter until I have worked out what I did wrong. As far as I know I have just upgraded to the latest versions (except of Joomla, I am one version behind until I have this under control), so any help welcome.
