@piyush try installing with npm after opening a terminal in your nodebb folder.npm install nodebb-plugin-whitelist-email-domains
then go to plugin page and activate it, rebuild and restart.
dbsearch installed plug-in for searching, but by default it is not looking for anything. If you select "All Categories" displays all positions, even those that do not have the desired expression.
Please tell me what to do to search worked fine?
