It is recommended to use projects with HTML5 code after 10.1 SP2 HF18 (Build 10.1.2.391) because the Telerik/RadEditor text editor now also support HTML5 code and would not strip them out.
Yes. As the Management Server doesn’t really “know” languages, it’s possible to have English (UK), English (US), English (Wales), or German (Germany), German (Austria), German (Switzerland) and so on. Just assign a unique name and you can have as much identical languages as needed.
Go to SmartTree > Administer Project Settings > Language Variants We should have --> Europe - English Main language Can We change the same ? Yes We can Select any lang variant and click edit Edit Language Variant and Check the Main language Check BOX..
IMPORTANT: If you delete the main language, then you’ll not be able to modify the content of language variant independent elements!!! So set another language to be the main language before deleting the one that was formerly the main language.
