Upload for large files not going through

Hi there,

I have a problem with uploading large files to our Owncloud using the web interface.
When I try to upload a file that is larger than 10MB, the upload does not go through and I get that little yellow rectangle at the top (see images). The problem does not occur when I use the Windows sync app, but I want this fixed. There is also enough capacity left. Does anyone have an idea where to start?

System: Win7 - ownCloud 8.2.7


a first starting point is the following FAQ containing all known info about such upload issues: https://central.owncloud.org/t/how-to-change-upload-limits-and-fix-upload-problems/851

I assume you're not running your ownCloud server on Windows?

It mostly won't fix your issue as this is more an environmental configuration issue but anyway: Please always update to the latest available release before reporting any issues: https://owncloud.org/changelog/#latest8.2
