Introduction

Roundcube is a browser-based webmail client used in cPanel hosting. Over time, you may experience display glitches or slow loading due to cached data stored in your browser.

Unlike some apps, Roundcube does not have a built-in “Clear Cache” button. Instead, the recommended method is to clear your browser cache to resolve these issues.

Prerequisite

• Access to Webmail via https://yourdomain.com/webmail

• Login credentials for your email account

• Using Roundcube as the selected webmail client

• Access to your browser’s settings to clear cache
