fIXED NOW THANKS!
Hi! I have hosting with dreamhost & my domain through another company. Usually, my website just sits there happily after being put together a few months back.
It's wordpress based.
Today, I had an email to say that the webcalendar I had installed months back but didn't use had upgraded. I went to see if this made a difference and it seems to have replaced my wordpress database as the main page. Now none of my original wordpress links work; in fact I can't seem to find anything except this calendar.
What on earth do I do next?
