Unable to access login page or any posts

Hello,

Updated my blog yesterday. Today I go to access it and it has disappeared.

Unable to access the login page or any of my 70+ posts on any browser.
Last 3 years of work appears to be lost.

Here are some links to try:

Please help.

I am not tech savy so I do apologize ahead of time. I am sorting through similar post but am completely lost and, afraid to make even the slightest of moves for fear of losing all my work.

I am not sure which version I am using, perhaps 4.2.5??

Thank you.

Knighton
