Pic exceeds the maximum upload size for this site.

I am building a new site at https://ChristianGays.com. I'm using BuddyPress and trying to upload a profile image that is 300 x 300px at 72 dpi (90 kb). I'm getting an error [image name] exceeds the maximum upload size for this site.

I had a plugin "Image Upload for BBPress Pro" activated and restricted limits to 600 x 600, max 2 MB but I disabled that, and it hasn't made any difference.

My upload_max_filesize = 64M
post_max_size = 64M

Can you tell me please what is preventing this upload?
Thanks!
Will grant support access
