Hello,
I'm trying to install the mail server plugin. but when I click on install, it suddenly shows me a black console and goes off. and then, It shows installing where the install button is placed on the plugin installation page. after some time it refreshes and shows the same install button. nothing happens. i tried clicking the button several times. but the problem still remains. no logs, no warning. every time i click on install, it pop ups a console and suddenly close it automatically, and change the install button to installing, after some time the button turns back to install.
what shall i do?
