Update System Core From 6.5.11 To 6.5.12 not work.
Installation and Configuration
There are 2 ways to get it updated that I think might work:
#1 change to a default jamroom skin, then try the update again.
- I think there not being an image spinner in your current skin is causing issues with the update.
or #2
Download the open source version from here:
https://www.jamroom.net/networkmarket/core_download/jamroom-open-source.zip
Then upload that to your server via SFTP.
Then run the integrity check again and jamroom should be working.
You'll still need to contact your hosting provider about the server functions.
