Well, you are right, my previous comment referred to a brand new 4.11.1 installation for a customer (since I like webERP so much, I even recommend it to my customers
)
The question regarding the upgrade was related to my own "old" 4.10 installation. Thanks for clarifying, I will do as you suggested.
I wish I could contribute to the codebase, but unfortunately, other than the odd minor change (like including a dot in the regular expressions), I have not much advanced in this topic. So, I'm still a mere "consumer" - but quite a happy one
Thanks a lot!
