Update a theme
Any advice would be greatly appreciated.
You need to have your site connected to the community, once that is done the updates will appear when you log in, on the news flow screen.
You will also need to have your themes license assigned, find out how to do that here
To connect to the community, log into your site, and hover the dashboard, next to "extend concrete5" you should see some links to add-Ons and themes, click on one of them, and it will either show the concrete5 marketplace, showing that you are already connected, or ask you to connect, to connect enter your concrete.org login NOT your websites login,
Once connected to the community, and your license is assigned, log out of your site, log in again, and wait for the news flow screen to pop up, it will then show you any updates available for your installed add-Ons/themes.
If you did not purchase from the concrete5 marketplace, it will be best to get in touch with the developer you purchased it from.
