thanks whooami and flashpal,
I forgot to say that it was working after it was initially set up by my host (Supanames). It stopped working when I tried to change the file “header.php” I played about with that for a while and got that back to how it should have been but still to no avail. I ended up putting the original files that I backed up, back onto server again, but still not working.
I’ve tried deleting all the pages and putting them back up again, but still doesn’t work. I’ve sent a message to my host to see if they can help.
HOpefully get it back on soon as I am really looking forward to using wordpress…
Thanks again.
