Thread: Can't edit or answer

I got a private message: "Dear L. whenever I try to anser somebody or to edit my posts I always get: "You are not permited this activity (or ssomething like this). Refresh the page and log in again". But of no use, I keen on not getting editing nor answering. What can I do? Thanks"

Can somebody help here?

May be his IP accidentally coincided with a mask banned IP?

It may depends on some things. Can't he/she answer a few questions?
What browser does he/she use?
What kind of device does he/she use? (Exp. Computer/Ipad/mobile(if this one, what is the model of the mobile?/ etc...)

It might all depends, he/she may also changed some of his device/browser's setting which is causing this problem.
But, as a default help, i would say; (hopefully if he/she use a PC or laptop)
Log out, Reset the computer, Reset the browser's settings, Sign in MR, and see what will happen!

But i really can't get it, he/she says:

whenever I try to anser somebody or to edit my post ...

So if he can't answer(Does he/she mean post?) what he/she is aiming to edit?
*Is he/she even got registered by Master Admin?
