I have followed the steps to set up my first discourse blog: https://xiaodingdangbbs.com/
However, I have an issue with the image upload. I have followed the instruction to change the limit to 20MB and confirmed on the server-side the discourse.conf in /etc/nginx is 20MB. However, it seems that I still have the issue uploading the image, even failed for a 900KB image. The only images I’m able to upload is under or around 150KB.
Also, when I click the “Upload image” button, some images with .png, .jpg extensions are greyed out although the extensions are correct and the sizes are under the limit. When I select them, nothing happens and no error shows up.
Any thoughts on how to fix this issue?
