Had to roll back to 2.3.5. I also noticed the ability to do a 301 redirect from the advanced tab is gone. I guess this was removed before V 2.3.5. I wish they would stop removing features. I was ready to purchased the premium version because I needed to redirect some URLs. Now I will not update, nor buy, until this has been resolved.
What was once free is now a premium option.
What a shame.
