Newbie struggling with public hosting

That is helpful to hear, thanks. I was looking into Fortrabbit a bit, will do the same with Liquid Web.

With the subdirectory on my godaddy site, here is the error I get in the browser:
Parse error : syntax error, unexpected T_OBJECT_OPERATOR, expecting ‘,’ or ‘;’ in /home/content/88/3875188/html/waarc/index.php on line 5

I’m wondering if, for whatever reason, my hosting doesn’t have a modern enough version of PHP.
