Hi,
When try to search over “Use Basic Search” i get an error:
“Fatal error: require(): Failed opening required ‘modules/Opportunities/metadata/listviewdefs.php’”
When i move “Opportunities” module from “Enabled Modules” to “Disabled Modules”, search works well without any error.
Any help or tip is welcome.
Hi, welcome to the Community! 
What is your SuiteCRM version?
Does the file modules/Opportunities/metadata/listviewdefs.php exist in your installation? It should be there with this content.
Make sure it is readable by your web server. You might simply be lacking a proper set up of your ownerships and permissions, especially likely if this is a new set up. If this was the case, you would probably also be seeing a bunch of undefined labels in several screens.
Also, try a Quick Repair and Rebuild from Admin / Repairs.
