Is that a c5.6 site? (has ADODB calls in trace)

It could be that your new server is running php7, which is much stricter than php5.x on function parameter type compatibility.

If so, you have 2 choices
a) reconfigure your new server for php5.6
b) manually update the core of your site to use c5.6.4 (from the 5.6 github, not officially released).

(a) is the simplest approach
(b) is the best for the long term and gives a speed advantage
(b) could have compatibility issues with some marketplace packages, such as core eCommercehttps://www.concrete5.org/community/forums/legacy-version-5-6-x/hack...

how do I trace? Changed this site to php5.6 I think and still received error . Cpanel said all were php7.
The site is C5.6.2.1

Those kind of error messages only come from php7+, so either the change you made in the cPanel was incorrect, or it hasn't taken effect yet.

could the same response come from php5.6? testing the old site it is still PHP Version 5.2.17!!! Just actually queried the site with phpinfo. OOPS cpanel did not do it. Good call. I will get it fixed.

you were on the money. ISP fixed the change and it did actually change. now it is working. on to a permanent fix.
