Web site

I hope this is in the correct heading!
I made and published my website about 6 years ago using page plus. In the first year I had to access the site twice to make a couple of changes, renewing my subscription every year with no problems. Things have now changed and I need to make changes to the website.
Failing memory and the passage of time leaves me perplexed.
I have never used page plus since then and I am totally at a loss as to how I can access the site on page plus to make the necessary changes.
Guidqnce would be appreciated.

TIA
