It happened to us too. We had a defunct Weebly account. Weebly banned our account for unknown reason without notifying us. Just completely behind our backs. But square portion of our account continued to work for months. Then we created online checkout links and they worked for a while. Then they just suddenly stopped working. Again, without any known reason, without notification or an explanation or any contact with us.
After hours of wasting time with customer service one discovered that it was because our Weebly account was banned. It was banned long ago and we don’t know what did we do wrong. We kept everything perfectly clean and clear. But as it was explained probably due to tighter Weebly integration (what a disaster it was!) our checkout links stopped working. Interesting enough Square reps told us that the ban cannot be reversed, even though nobody could explain to us why it was banned to begin with. No appeal process, no communication from square - nothing. We were advised by Square just to abandon our account and create a new one. What a hassle!
