Good to hear now all well. Usually a exit and re-login will fix that if it ever occurs. I’ve seen it myself about twice in the last three years but we haven’t been able to recreate it to determine exactly why it occurs.
When an AyaNova user logs in, at that time the locale set in their User entry screen is enforced - as the locale sets what text displays for all labels. Its possible thata problem with a network connection to the server can cause a hickup, or something lagging on the server causing a slower response from the database.
Do a quick check on your server and make sure it is not overloaded - i.e. memory free, CPU %, etc just to confirm. But I won’t expect it to re-occur.
Have a good weekend
