Email add button not working in Accounts

After upgrading to latest version 7.7.8, it seems there was a bug in Accounts. The + button for Email isn’t working.

there may have been an issue with you upgrade and the javascript was not rebuilt,

try clearing your browser cache then with Admin->Repair doing a “Quick Repair and Rebuild” and a “Rebuild JS Grouping Files”

Thanks for replying Matt. Yes thanks. clear cache of the browser solves the issue
