After site replication (export-import) we got following error in summary link web part
Unable to add selected web part(s). Could not load XSL file. The system cannot find the file specified.(Exception from HRESULT: 0x80070002).
Solution:
This error basically related to site publishing feature
When we try to add a publishing-related web part (such as Summary Links) into a non-publishing site. You have to either add it into a site built with a publishing template (Collaboration Portal or Publishing Portal), or to activate the publishing features manually
Activate Office SharePoint Server Publishing Infrastructure feature in site collection features, in Site Collection Administration section of Site Settings page
Activate Office SharePoint Server Publishing feature in destination site features, located on Site Administration section of Site Settings page
