This isn't really an error. It is letting you know that the file that you are trying to upload exceeded the allowed limit. I have checked your site and it looks like the limit set under the ACL for the "Event and community profile" was set to 5mb, http://take.ms/hBFAN

If you want to allow larger file uploads from your users, you can increase this value up to 128MB (Your current server is limiting upload limits to 128mb)

I have change the setting, and now it didn't allow me to upload more than 6 pics. but I see that it doesn't have limit on the amount of pictures... so what's wrong in the settings? Is it 128 mb per file or per upload?

Hi Itamar,

The setting is for per file. I checked your profile type again and it looks like it's still set as 5mb for photos(http://take.ms/FhOlR).

If it still does not work, perhaps you can send us the photos so we can try uploading it?
