After further investigation (could update slate and ar-750 to updated secure plugins wit no problem, both using standard “release” Firmware) I noticed:
This issue relates to this one mentioned here:
Basically:
For gl.iNet mv-1000/Brume, there is no updated/secure list of plugins?
Can you please confirm & give an option to update those plugins?
I thought the problem concerned the pre-release"testing" firmware of mv-1000/Brume.
So I reinstalled the official “release”-Firmware … but even then: The Plugins-list does not reflect the secure versions necessary (2.4.7-13)
Thanks for a reply
