[opencms-dev] [NEWBE] Error reading resource from path "/demo_en/intro.html" with opened Workplace

[jacek grzebyta (RRes-Roth)]

Hi guys,

I am trying install & config OpenCms and I don't understand why I cannot open demo site after opening OpenCms Workplace of (Admin).

I just login without any work and I cannot open /opencms/opencms/demo_en/intro.html and /opencms/opencms/sites/default/demo_en forwards me to the first path. But when I logout from the workplace and everything works fine. It is just plain configuration without any modifications. I don't have this error if I am login to normal user account (I mean workplace user + project manager).
The full log is:

Error 
Error reading resource from path "/demo_en/intro.html".
Reason: Unable to read resource "/demo_en/intro.html".
