2 web servers, 3 application servers, 1 OWA server, 1 DB server. Upgraded a site from 2010 to 2013. On one web server, I am getting:
Could not load file or assembly 'Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' or one of its dependencies. The system cannot find the file specified.
This is happening only on the upgraded site.
If I create a new site collection in SP 2013 mode on the same web server, it is working fine. Eventviewer Application logs are not helpful.
Thanks, Soumya | MCITP, SharePoint 2010
