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
