I need 15 GB limit per my Enterprise storage limit so I dont violate my advertising for last year (don't think that's problem I think its at 14.65gb). It says failure to upload after uploading a 815kb picture on yf homepage. This has gone on for over week, lets end it : ) !!
I dont know what folder and who these people are? WP or my host?
I don't see the rewrite rules in htaccess.
question: can there be more than one multisite on server? My add-on is current. Primary is not, is that ok, is there a rule I heard it has to be on the root or primary level and not add-on domain such as here? Checking. Would like an additional Multisite on Primary thanks.
Regarding the upload limit (which I should note, is for the maximum size of the file being uploaded, not the amount of upload space granted to a site, big difference), I was able to get into settings for the network for the subsite you mentioned, and I set the "Max upload file size" to 1500 KB, and I'm not seeing the "Maximum file upload size" come up as blank anymore.
Regarding the issues with the uploads, it appears that they're using an older upload folder path, I had to insert this into your .htaccess to get WordPress to use that properly:
# uploaded files
RewriteRule ^files/(.+) wp-includes/ms-files.php?file=$1 [L]
