How to add the highlighted navbar store button
Settings to enable the store button are in Cobalt settings -> header -> navbar
If those don't work:
Verify the Link
If you are using the Tebex, Craftingstore, MC Trade, or the store module, make sure the store link in cobalt settings is /store/
External Stores
If you are using an external store, make sure you create a redirect link to it in StaffCP -> custom pages. Then, make sure the store link in cobalt settings is set to the link of the external store, NOT the link's url on your site.
