I searched, I found some info, but still I am stuck. I know the answer is probable somewhere in these forums, but I am bit overwhelmed with other unrelated distracting issues.

My host switched everything over to a new server last weekend, store appears ok, but no one can log in, nor I into Admin.

I did the following and wait the Host reply for help, but wonder is there something I am overlooking.

I went to the (2) ZenCart configure.php files and changed the https references from the old "serverxx" to the new "serverXYZ"

Before these edits, page would not load when trying to log.
But now, after edits, when I try to log in to Admin or as customer, I get the following errors.

Warning: Unknown: open_basedir restriction in effect. File(/home/mypassname/public_html/catalog/index.php) is not within the allowed path(s): (/usr/local/apache/htdocs:/usr/lib/php:/usr/local/sqmail:/usr/local/lib/php:/tmp) in Unknown on line 0

Warning: Unknown: failed to open stream: Operation not permitted in Unknown on line 0

Fatal error: Unknown: Failed opening required '/home/mypassname/public_html/catalog/index.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in Unknown on line 0
I did ask the Host if they had the shared cert up and running, but only recently and yet to get the reply.
Does these warning ring a clue to anyone that may help me get this store running again?
Thanks,
