Hi, I am looking for some guidance on what to do for an older version of Concrete5. We recently noticed the pretty urls are broken on the site. Going to the domain shows the "under construction" concrete5 page. Adding ...index.php to the url shows the correct page. I tried turning off pretty urls, clearing the cache, and refreshing, but it did not help.

I also tried updating PHP to 7.0, 7.1, and 7.2 but each of those caused the whole site to go down.

The website is still on http.

Any tips on the best way to resolve this or update things so they work are appreciated. Thanks.

Some details:
The site is hosted on Bluehost, and I think I used Simplescripts to set up the Concrete5 site, and I can't log into SimpleScripts on cpanel, so I am not sure that is available any longer.
