Hi lemmy.world folks,

I'm having an issue creating a new post in [email protected].

1. Cross-instance posting from my home instance (https://szmer.info) only creates a post in my home instance's view of @lemmy.world. After 10 hours the post still doesn't appear on @lemmy.world.
2. I've created a local (@lemmy.world) account and tried again - but then the Submit button spins forever. The post doesn't appear in the community.
3. Using the "Photon" UI I get an error pop-up saying simply "couldnt_create_post".

To the best of my knowledge I'm not banned.

Do you know what coud be going on and how could I regain my ability to post?
