Hi,
I have now tried switching to mobile data, unfortunately still no success. I have also tried a third device (a hp PC through chrome) and again I am still unable to delete. The same error message appears as above.
This is my uneducated guess. A little while ago, I was scrolling through a thread and I found an attachment that I decided to delete. But instead of deleting it the correct way - in my attachments folder, I was lazy and removed it by just editing the post (it must have been a recent enough post for me to do so).
As I say, that would be my guess, I’ve somehow “locked” myself out of being able to delete things?
My only other guess is there is an attachment still active that belongs in a thread that was deleted/deactivated. It was the “9 points” thread posted in on topic and I posted in that on 22nd March. I am also unable to delete that GIF despite the thread no longer existing (or maybe because the thread no longer exists?).
Like I say, total guesswork on my part, but they’re the only two instances of recent activity where something different has happened with an attachment.
