Having had a perfectly Stable and working server and Roundcube, for quite some time,... sometime around the 20th or 22nd of June, It became impossible to actually view, New OR Older emails via Roundcube.
The GUI interface loads and runs fine for All accounts but am 'presented' with;

The above error warning appears when trying to view any Folders or defined storage areas withing the Roundcube GUI.
Perhaps strangely, emails CAN still be sent and the interface works fine.

Anyone have ANY ideas or suggestions ??
