I tried "The first thing to try is an upgrade install by going to
http://yourdomain.com/setup. There’s a good chance that will straighten out the paths.
If not, check the paths in core/cache/config.inc.php
and the four config.core.php files:
§ MODX root directory
§ /manager/
§ /connectors/
§ /setup/includes/ "
and it did not work, have you got any other ideas?
thank you
