@piyush try installing with npm after opening a terminal in your nodebb folder.
npm install nodebb-plugin-whitelist-email-domainsthen go to plugin page and activate it, rebuild and restart.
Re: [nodebb-plugin-gallery] Lightbox Gallery Plugin
It seems the plugin is not working for me.
So when creating new topic/reply and I click "picture" in the composer, the image will not open in a lightbox.. I need to go back and forth to see another image
And if by "upload image", the image will open in a lightbox, but at first it will open in a new tab.
I install the plugin via ACP.
Thanks
