'The submitted form was invalid.'

[Kanassa]

I hope I'm posting this in the right place, if not, my apologies.

Recently, I've found that I am unable to delete my private messages, both individually and multiple. Any time I try, I'm just taken to the 'The submitted form was invalid. Try submitting again.' screen. I've tried clearing my cache/cookies, resetting my internet, logging in and out, ect. Is this a common problem or is something on my end screwing up?

Gonna bump this since I've been having the same issue

I'll look into what's going on here. It does appear to only be doing it from the main PM page if you check the boxes. If you open up a specific message and then click the "X" to delete it, it works normally and you can delete it.

I'm experiencing this right now in trying to delete the flood of PMs sent to me by another user repeatedly harassing me.

EDIT: OK I found out you can delete messages individually by clicking on them and then clicking the X button, but its still annoying to not be able to delete multiple messages at once.
