I think you'd run into other problems with the Manager if it was a MODX path problem, but you can check the paths in core/config/config.inc.php.
I think it's more likely a path problem with those addons. Edit their elements and check the "Properties" tab to see if there are any paths there. Then check the System Settings to see if there are any path settings specific to those components.
If that doesn't work, I'd try uninstalling, removing completely, and redownloading/installing them.
I'd also check the path in the modx_workspaces table in the DB.
Another way to go, if you know how, is to go into PhpMyAdmin and search the DB for your old path (the one from the dev. server).
