Kopano-WebApp by default is shipped with following .htaccess file on its root.
# some apache settings Options -Indexes # The maximum POST limit. To upload large files, this value must be larger than upload_max_filesize. php_value post_max_size 31M php_value upload_max_filesize 30M # Deny access to config.php, config.php.dist, debug.php, debug.php.dist, defaults.php # because they could become a security vulnerability when accessible # Better safe then sorry <FilesMatch "^(config|debug|defaults|init)\.php"> <IfVersion < 2.4> Deny from all </IfVersion> <IfVersion >= 2.4> <RequireAll> Require all denied </RequireAll> </IfVersion> </FilesMatch>
Anyone who is using php-fpm instead of Apaches mod_php will get into trouble, because you cannot access Kopano-WebApp. The error produced in the log clearly states, that the lines “php_value” are unknown to php-fpm and cannot be processed. Thus you get an error page with Internal Server Error when trying to access Kopano-Webapp through your browser.
That’s nothing new and certainly known to most of us. You have to remove (or disable by commenting) all php_value lines from that .htaccess file and put them into the php-fpm configuration so they can correctly be processed by php-fpm. I am using separate php-configuration for my Apache2 web server running which are defined under /etc/php5/fpm/pool.d For the sake of completeness, the corresponding configuration file for php-fpm is:
[...] php_value[post_max_size] = 31M php_value[upload_max_filesize] = 30M [...]
I have following simple suggestion to the developers, maybe they can look into it and implement it in future version?
In /usr/share/kopano-webapp/.htaccess change the corresponding lines:
# The maximum POST limit. To upload large files, this value must be larger than upload_max_filesize. php_value post_max_size 31M php_value upload_max_filesize 30M
<IfModule mod_php5.c> # php-fpm users should consider putting these settings into their appropriate php-fpm configuration php_value post_max_size 31M php_value upload_max_filesize 30M </IfModule> <IfModule mod_php7.c> # php-fpm users should consider putting these settings into their appropriate php-fpm configuration php_value post_max_size 31M php_value upload_max_filesize 30M </IfModule>
As result, these php definitions will only be effective in Apache in case the internal php module is in use (either version 5 or even the latest version 7).
Why I am suggesting this? Because just some minutes ago I stumbled again over this. I upgraded Kopano-WebApp to the latest version and after the upgrade the webpage Kopano-WebApp was not accessible any more with “Internal Server Error”. The default .htaccess settings did overwrite my old .htaccess file, where I had removed those two lines.
