[SOLVED] Update 7.0.9 to 8.2.4, problems with feature not available - by: Rand

Hi,

I faced issues when i updated projeqtor 7.0.9 to 8.2.4.
When i click for example on "Absence" it says:
"This feature is not available in this version of ProjeQtOr, Sorry... "

I already checked similar post and cleaned the cach of the browser but it didn't worked.

Any suggestions to fix this problem ?
