   <description>When a folder contains too many message (not sure what the threshold is), I get a blank page (no error message, nothing) when trying to view the content of the folder.
When #of messages &lt;1500, by navigating to another folder and coming back to the desired folder normally solves the issue.
In this particular case, I hadn&#039;t clean my Trash folder in several days and 4400 emails had accumulated. I was not able to access my Trash folder from Horde but only from a shell.</description>

   <description>I have finally been able to reproduce the blank page error consistently.

I recently received one email with a 8+MB attachment.
Every time I try to open this email in horde, I get a blank page.

Looking at the logs, there is nothing in either
/var/log/apache2/error.log
or in
/tmp/horde.log

/tmp/horde.log contains only login success and logout lines.
This is totally useless!

From this behavior it is clear that there is a memory limit that stops the execution to a 
blank page.
Shouldn&#039;t the error be catched and an error message returned to the user instead of a blank page?

In my conf.php file, I have:
$conf[&#039;debug_level&#039;] = E_ALL;
$conf[&#039;log&#039;][&#039;name&#039;] = &#039;/tmp/horde.log&#039;;
$conf[&#039;log&#039;][&#039;type&#039;] = &#039;file&#039;;
$conf[&#039;log&#039;][&#039;enabled&#039;] = true;

$conf[&#039;fetchmail&#039;][&#039;size_limit&#039;] = &#039;10000000&#039;;    
$conf[&#039;compose&#039;][&#039;attach_size_limit&#039;] = &#039;0&#039;;

So my questions are:
1) How can I disable the NO error_reporting() in horde?
 Where is the switch that would put back horde in testing mode?
2) Why the error(s) is(are) not reported in the logs (horde or apache)!

It will if error_reporting in PHP is set to output errors to the page.

It will be reported to wherever *PHP* is configured to log to.</description>
