I have migrated from a Windows Server to a LAMP server. There were no errors during migration. However, after migration each time I edit or save something in Sellacious backend, I get an error the first time I load any page (Backend and Frontend) that is related to Sellacious - the second time on wards till I again save / edit something in Sellacious, it seems to works fine . The error indicates to the template.

However, the other pages not generated / related to sellacious work just fine immediately after editing / saving.
Can you please help me in troubleshooting this issue?
