Hi Skaero
Thank you for replying.
the reason i did not post anything from the errors.log was.

cd /var/www/html/webmail/logs/
[root@host logs]# cat errors.log

[root@host logs]# ls -al
total 44248

in addition to your question, ill assume you might want my log settings.

from /var/www/html/webmail/config/config.inc.php

$config['debug_level'] = 10;

// Log SQL queries
$config['sql_debug'] = true;

// Log IMAP conversation
$config['imap_debug'] = true;

// Log LDAP conversation
$config['ldap_debug'] = true;

// Log SMTP conversation
$config['smtp_debug'] = true;
$config['log_driver'] = 'syslog';
$config['syslog_facility'] = LOG_MAIL;

and from php.ini

error_reporting
   Default Value: E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED
   Development Value: E_ALL
   Production Value: E_ALL & ~E_DEPRECATED & ~E_STRICT

 log_errors
   Default Value: on
   Development Value: On
   Production Value: On

the logs i gave in my first post come from maillog, but they are pretty much the same as what goes into imap.log.

the apache logs may be off assistance to you, but i cant fathom out where they are comming from, in the maillog there is a line as follows.

Mar 12 10:19:51 host roundcube[108700]: <l9ik2lel> [7B74] C: A0002 ID ("name" "Roundcube" "version" "1.6.6" "php" "7.4.33" "os" "Linux" "command" "/webmail/?_task=mail&_caps=pdf%3D1%2Cflash%3D0%2Ctiff%3D0%2Cwebp%3D1%2Cpgpmime%3D0&_uid=6137&_mbox=INBOX&_framed=1&_action=preview")

and that lines up with the 500 error from httpd as follows.

ipaddress - - [12/Mar/2024:10:19:51 +0000] "GET /webmail/?_task=mail&_caps=pdf%3D1%2Cflash%3D0%2Ctiff%3D0%2Cwebp%3D1%2Cpgpmime%3D0&_uid=6137&_mbox=INBOX&_framed=1&_action=preview HTTP/1.1" 500 634 "http://host:/webmail/?_task=mail&_mbox=INBOX" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/122.0.0.0 Safari/537.36"

the apache error log has no error log matching the event, the last log to it was yesterday when i restarted httpd, so not relevant to today's replay of the error

Whats in the Roundcube error log located at <RC root>/logs/errors.log

Hi , This is my first post, ive joined here because I have a problem with roundcube and I cant find the specific problem , using google.
I have a postfix daemon delivering mail into a Dovecote imap server, and connected to those two daemons via smtp/imap are aquamail on phones and tables,
Thunderbird on Desktops and every thing is fine with those, they dont have this specific problem at all.
when reading mails ive recieved from outside of my systems, ie from the internet, roundcube displays the mails without a problem.
but any system generated mails from any of my linux PC's which display on all other clients fine , just gives :
Oops... something went wrong!
An internal error has occurred. Your request cannot be processed at this time.

For administrators: Please check the application and/or server error logs for more information.

Also if i use the right click on those mails and more edit as new, it displays the mails without a problem, heres one just as an example.

if I now send that mail to myself from the edit as new form, via roundcube, the new mail received from it displays without a problem.

what imap actually sees in the logs is the following. (edited for privacy  -- where host is used)

I really want to switch from thunderbird to roundcube, so any help in how to diagnose this would be great.

ive enabled all the debugging suggested by many a forum post, but still cant see where this is happening.

regards peter

ps system is Rocky 8.9, PHP 7.4.33 , apache httpd 2.4.37-62, dovecot-2.3.16-4,

Hello, I have been using Roundcube through Hostgator for many years and grown very comfortable with it.

Due to issues with Hostgator's email reliability, I just switched to MXRoute, which also hosts the new Roundcube 1.6.  I am aware that some of the old skins were removed as options.

I cannot find any way to add list columns or remove the preview pane in this version.  Is there any way to customize these?

Thank you.
