After august update my video addon list is empty.
The addons are still there. I can use them from the favorites list.
But the video addon list is empty.
I checked my log to see if any error popped up and I got this error on all my addons:
23:04:32 31.055586 T:1438643184 ERROR: Couldn’t load /home/osmc/.kodi/addons/service.library.data.provider/1080/Font.xml
I changed skin to confluence and back to osmc’s skin but the addon list is still empty.
Tried to search for similar issues here and on google but no luck 
That error is unrelated. Please provide a complete set of logs.
Check for updates. I suspect your system isn’t fully updated.
My OSMC -> Manual Controls -> Updates -> Check for Updates now.
Just checked. My Osmc says there’s nothing to update.
What are the commands to force a command line update?
What logs do you need? just kodi.log?
As @ActionA says, you need to provide a full set of logs.

Your system is not up to date. The correct version should be 16.1.0-20. Check for updates again, and also check your network connection. If you’re on WiFi, try an Ethernet cable temporarily.
You can also update via the command line with sudo apt-get update && sudo apt-get dist-upgrade

Thanks for the help @sam_nazarko and @ActionA
