X6 wiped site in incremental update

I made a couple of minor changes as I didnt like the way my hyperlinks looked.

Did an incremental update and it has reverted my whole site back to the original holding page I had (not designed or published by X6, but Wordpress).

None of my settings have changed, I did several updates over the last few days as this is a new site, and they were fine.

I can only think that I must have accidentally clicked on something that has done this, but I dont know what!

Please help, this is a majorly important site for my business

Thanks
