Okay. Sorry for this. Solved this with a little bit more of error checking.
Was just a coding issue of something in a theme page file I had that the Host’s server couldn’t handle.
Just for FYI and a bit off subject, I had
<?php
/* code stuff here and commenting out the next 80 lines
The code was not commented out and no ending ?> tag.
Was no problem on my laptop localhost which I though was odd, but was a problem on the host.
