WHM Roundcube Blank Email Fix

All messages viewed through Roundcube are loading as completely blank for every mailbox on the server. This started right after I adjusted a few WHM /- cPanel settings, so I’m sure something I changed triggered the problem. I need someone to trace the root cause inside WHM, cPanel and Roundcube—whether it’s a dovecot/IMAP hiccup, missing MIME handlers, cache corruption, or a permissions mix-up—and restore normal message display without losing any data. Deliverables • Diagnosis summary explaining what went wrong • Configuration changes or patches applied (with exact file paths or WHM panels noted) • Confirmation that emails now render correctly in Roundcube for multiple test accounts Please be ready to work directly on the live server and keep downtime to a minimum.
