Roundcube issue - mail missing

[cPanelDon]

ok, turning the caching off instantly fixed the problem for the one client having troubles. How can we make this permanent so that the next time cpanel updates it will not overwrite my setting?

Thank you for the feedback and information. As was suggested by Craigles, it is possible to automate customizations after an update using the built-in script hooks, such as preupcp and postupcp. For additional clarification please reference the following documentation:

• Hooking into cPanel Functionality
• cPanel/WHM Script Hooks

You could try adding those commands to /scripts/postupcp - that way any cpanel update will call that file after completing it's routines.

#!/bin/sh

cp -pv /usr/local/cpanel/base/3rdparty/roundcube/config/main.inc.php /usr/local/cpanel/base/3rdparty/roundcube/config/main.inc.php.backup

perl -p -i -e 's/^\$rcmail_config.*enable_caching.*TRUE\;/\$rcmail_config\[''\'\''enable_caching''\'\'']\ \=\ FALSE\;/g' /usr/local/cpanel/base/3rdparty/roundcube/config/main.inc.php

That's how I would do it anyway - i'm sure one of the cpanel tech's will correct me if I'm wrong

For purposes of automation in a custom script using the built-in hooks (e.g., "/scripts/postupcp"), I would revise the suggestion to the following example that I believe should work with minimal difficulty:

#!/bin/sh
/bin/echo
/bin/echo "Post script running..."

/bin/cp -fpv /usr/local/cpanel/base/3rdparty/roundcube/config/main.inc.php /usr/local/cpanel/base/3rdparty/roundcube/config/main.inc.php.backup

/usr/bin/perl -p -i -e 's/^\$rcmail_config.*enable_caching.*TRUE\;/\$rcmail_config\[''\'\''enable_caching''\'\'']\ \=\ FALSE\;/g' /usr/local/cpanel/base/3rdparty/roundcube/config/main.inc.php

/bin/echo "Post script completed..."
/bin/echo

Roundcube cache errors still are a problem on several servers. Turning off caching fixes the problem, but every roundcube update turns it back on...

To the best of my knowledge I believe that caching in Roundcube is now disabled by default, at least I see it is disabled when forcefully re-installing Roundcube in cPanel & WHM version 11.28. As the IMAP/POP mail server, Courier or Dovecot, is hosted locally, that is in the same system that serves cPanel, I believe that Webmail should not require additional caching in Roundcube over what is already handled by the local mail server.
