Uploading Image Issue

Dear Support Team,

I am having the following error notification when I am trying to upload an image of 2M on my WordPress Media Library: "Dr Green Final Website Preview.png exceeds the maximum upload size for this site."

I have tried increasing the memory_limit to 3000M, the post_max_size to 2000M, and the upload_max_filesize to 1000M but the issue persists.

Could you please provide support?
