Not receiving e-mails of forum posts

I have not received any e-mails of forum posts for quite a while. So, I went into my account settings, and all three forums are set to send me all messages. So, my account settings are correct. ---------------
When I click on SAVE to save these again, the following warning messages show up (running in Chrome Browser):
