I've installed 2.6 two days ago and went abroad. I came back home today, checked Google Analytics to find out my traffic went to near zero.
Apparently all works, it is just incredibly slow.
Is it safe to replace files back with the 2.5.1 files and go to admin to change the db schmema?
Will the database downgrade automatically?
2.6 introduced quite some changes, but they are all useless to me anyway, so I am happy to downgrade.
