We apologize for the inconvinience caused by Galaxy LEfSe and are currently working on fixing the issue. Please consider using MaAsLin2 (http://galaxy.biobakery.org/tool_runner?tool_id=MaAsLin2) as a long term alternative for LEfS
MaAsLin2 is not accessible
Hi @samia418
If you are working at the Biobakery Galaxy server, you should ask those scientists directly about the status of tools since they will know best. 
This is how to find their forum →
If I have misunderstood and you are working somewhere else, would you please clarify a bit more about what is going on? A shared history link will provide all of the details but you can also include screenshots – just make sure the URL is showing at the top of the browser window. Please see → How to get faster help with your question
Let us know how this works out!
