After save some additional items like plugins or meta, capabilities are deleted.
when I click in update in meta boxes box or plugin list box, the page refresh and all of my capabilities in this role gets deactivated. i need to choose all again.
Unfortunately, I can not repeat this at my test environment. If it’s possible to look at the issue on site (dev. copy preferred), send credentials to the support [at-sign] role-editor.com
The same result. If you can repeat this at the development copy of the site it would be good to get admin access to investigate the issue. If it’s possible send credentials to the support email address.
