Today I was trying to work on my database and certain tables would randomly not allow me edit any of the fields. I wouldn't receive an error message it would just make a sound and nothing would change (adding, changing or deleting).
Later those tables would suddenly start working again and others would stop working. And also sometimes I'd be working on a table, change a few values and then it would lock me out abruptly. Just seconds after I'd just changes some fields.
What's going on here??
