Lost webpages

Went to update the church website this evening and found that it had completely disappeared. We have been using a free web hosting service (not ideal but was a temporary measure whilst other options were investigated) and it seems they have changed their system. The website address now redirects to their website maker page, and logging in using the previous details results in an error message. I’ve produced a very basic page in the meantime with church information. There may be some way of retrieving the pages, but it looks like I will be redesigning the website sooner than anticipated!
