Just to clarify…if I download 3.8.1 I will not have this problem?
We encourage our users, when developing in a critical environment, to have side-by-side installations so if a feature does not work out, or breaks something rolling back their install is not a hassle. While we *did* disable the indexer in 3.8.1, I cannot say that you might not run into OTHER problems and honestly I would feel bad if I said “sure no problem, have at it” and then you just ran into another problem.
If you are working successfully with your install now, please stay with it until we can stabalize ME and all the new features a bit more (we replaced/rewrote almost 60% of our code base… it might take af ew months). Our 3.8.2 goals are performance, our 3.8.3 goals are bugfixes and missing features and 3.9 is purely features and bugfixes.
