Hello, I have successfully installed Limbas 3.3.16.345 on a Centos 7 VirtualBox machine and the application operates as expected. I am trying to translate the application to Greek by creating a local language table. Problem is that I cannot create a new language from within the Admin > Language > Local Language submenu; the new language entry is not created at all. Can someone direct me what I am doing wrong? Thank you very much in advance.
