When I try to update the Author's Notes for a page of my comic, pressing 'Send' doesn't actually work. The old notes just pop right back into the frame, the changes I made completely gone.

I have no clue what I could be doing wrong, as all I do is a make a change and press send. If anyone could help me out with this, I'd be very grateful :)

Heeeey, nice comic :)

OK, no idea what's wrong. I have two suggestions though:
1. delete your cookies.
2. try doing it with a different browser and see what happens.

To delete your cookies... Well it's different depending on the browser and I haven't got the time to write it here, so you'll have to check the help files, sorry. :(

Nope, I've tried clearing cookies, I've tried from a different browser, I've tried from a different machine altogether, but it still doesn't keep the changes :(

Is it possible it won't accept the changes because the page in question isn't live yet?

Hmm. That could be the reason.
In that case you'll have to delete the page and then re-upload it with the correct info on there. Make sure you set it to upload to the same date though, so it goes live at the right time :)
