SwitchtabLink not working...
Fragment of a discussion from Extension talk:Header Tabs
It is now working. Our issue was that we had $htUseHistory = false;. Once I switched it to true everything worked. So I am not sure if this is an error based on the documentation:
The $htUseHistory variable defines whether tab navigation should be tracked within the browser history and within the URL, updating the hash value.
I would think this setting should not cause switchtablink to work or not.
