Hello,
Running 0.9.4 here and I enabled the "help" plugin (part of the distribution) to see what that currently looks like. Both using the stock version and the latest from github, if I enable the plugin using the stock config.inc.php, I end up with the following errors:
[30-Oct-2013 22:10:37 -0400]: PHP Error: Failed to load config from /usr/local/www/apache22/data/webmail2/plugins/help/config.inc.php in /usr/local/www/apache22/data/webmail2/program/lib/Roundcube/rcube_plugin.php on line 121 (GET /?_task=help&_rel=mail&_action=index)
[30-Oct-2013 22:10:37 -0400]: PHP Error: Error loading template for help.help in /usr/local/www/apache22/data/webmail2/program/include/rcmail_output_html.php on line 489 (GET /?_task=help&_rel=mail&_action=index)
The config file exists:
[root@mbox /usr/local/www/apache22/data/webmail2/plugins/help]# ls -l /usr/local/www/apache22/data/webmail2/plugins/help/config.inc.php
-rwxr-xr-x 1 root staff 1468 Oct 30 22:10 /usr/local/www/apache22/data/webmail2/plugins/help/config.inc.php
The error returned in the browser is:
SERVICE CURRENTLY NOT AVAILABLE!
Error No. [501]
I'm not sure if this plugin is a work in progress or not, so perhaps this is expected.
