[opencms-dev] javax.servlet.ServletException: javax.servlet.jsp.JspException: VFS target "/system/modules/org.opencms.frontend.templateone/templates/main" was already included earlier.

[maria.freixes_graells at alcatel.es]

Hello,

I've modified the properties file (the template site) of:

/system/modules/org.opencms.frontend.templateone/templates/main

and then I've restored the previous one, but now, it describes an error, 
I don't know why, because it's the same that older one.
Could you help me, please?
