Wb site blank

Hi

I have a site which contains some videos for an old membership community I worked on

Got an email saying, “Why is the login page / site all blank?”

I am not sure what I did or did not do to make this happen

Anyone got any ideas how I can get my site to appear again?

I looked on the host (GoDaddy) and all the WP files seem still to be in place

Thanks in advance

Phil
