I am receiving an error message stating "Oops...Reached your limits." How can I correct this?

When trying to forward or reply to a file submission, the following error message is displayed:  "Oops...Reached your limits"  (screen shot attached)

When checking our site activity, we have only received 37 file submissions in the month of February.  Is there a step we need to take to remove this error and restore functionality?

Thanks in advance for your time!

Rick
