Please give me the pic8 link you try to share. I need to check it, because it's causing the function that is responsible for the thumbnail generation to fail.
I've just checked that link and this album doesn't contain a single image, which is a known and very rare bug when you try to add more images after creating the album.
I did not add to an existing album. I'll try to upload again.
Ahhh...pic8 album link indeed.
If the first image is corrupt or missing, it can cause an issue with the post's thumbnail generation.
I just added a special exception in case that happens. The post will go through from now on, but it won't have a thumbnail, which will be easy to spot when it happens.
Thanks for the report!
You're welcome, thank you! Do I get the "I broke Poal" badge now? lol
