Can't install plugins from plugin gallery (OJS

I am trying to install some plugins from the Plugin Gallery but unfortunately, I couldn’t.

I tried to install Text Editor Extras, Keywords, etc. But nothing happeningduring installation.

  1. Go to website.
  2. Plugins → plugin Gallery
  3. Clcik the Text Editor Extras,
  4. On popup, it is showing install button.
  5. Click the install. Nothing happening. It is like a statue.

What should I do now?
