This is a specific example of a pretty general problem when dealing with code. You have an error somewhere, and the error message points you to a line of code that is not super helpful. menu.inc is a file in Drupal core, so it is not likely that the bug is there. There are a few things to try:
- Have you verified that the error only appears when the Quoting/Estimate module is enabled? If not, disable the module and see if the error disappears.
- Have you looked in the issue queue of the module? Often others have encountered your specific problem. You can see if a patch has been created, or create a new issue to report the bug.
- Have you looked at the code the error message points you to? It looks like this:
return call_user_func_array($router_item['page_callback'], $router_item['page_arguments']);
It is basically calling a callback function as specified in quoting_menu to generate the page you are trying to get to. The error suggests that the function it is trying to call, quoting_quote_clear_page does not exist. Have you checked the module to see if that function exists?
