I started getting the error "Not enough space to upload. 726 KB needed." when trying to upload an image. There must be a quota set somewhere but I can't find it. Here's where I've checked so far:
1) The option for "Site upload space" under Network Admin > Settings is not checked.
2) The "Site Upload Space Quota" is blank (for network default) under Network Admin > Sites > Edit > Settings .
3) It's hosted on my own virtual server, and I've gone into WHM and the quota for the account is set to unlimited.
Any ideas? Thanks!
