It started with me receiving 5 emails notifications for a single comment posted by GeneK. Seeing all 5 were for the same post, I approved 1 and deleted the rest. I thought this as a one-off.
When Javi posted, he received a message saying that this comment has not been successfully posted. At my end, I received, again, 5 emails notifying me of the same comment requesting for approval. Javi dropped me a note via the feedback form to let me know about this. This is a strange behavior that I've not encountered before.
I've sent a note to Weebly support. Hope that they'll respond soon and fix this up.
Meanwhile, do keep your comments coming. They provide me with the motivation to do and post more.
