I'm having a problem when I click the Send button in Gmail it says it's working, then pops up a window saying "Your action was unsuccessful. Please try again." with no other option but to click the OK button. I've tried this 4-5 times in a row now with the same result. Does anyone know what this is or why it's happening to me?
Edit: It also is happening to me when I try to save the message as a draft. I have tried logging out and back in, and also clearing my cache first, but it's still happening.
