phpBB 3.1.7-pl1 500 error for app.php

any extension that uses app.php from phpBB 3.1.7-pl1 throws a 500 server error.

here's my .htaccess file if that is needed

# # av:php5-engine
AddHandler av-php54 .php

# av:PHP-upload
php_value upload_max_filesize 20M
php_value post_max_size 20M
php_value max_input_time 300
# PHP-upload
<IfModule mod_rewrite.c>
SetEnv HTTP_MOD_REWRITE On
RewriteEngine on

# Uncomment the statement below if you want to make use of
# HTTP authentication and it does not already work.
# This could be required if you are for example using PHP via Apache CGI.
#
#RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L]

#
# The following 3 lines will rewrite URLs passed through the front controller
# to not require app.php in the actual URL. In other words, a controller is
# by default accessed at /app.php/my/controller, but can also be accessed at
# /my/controller
#
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ app.php [QSA,L]

# With Apache 2.4 the "Order, Deny" syntax has been deprecated and moved from
# module mod_authz_host to a new module called mod_access_compat (which may be
# disabled) and a new "Require" syntax has been introduced to mod_authz_host.
# We could just conditionally provide both versions, but unfortunately Apache
# does not explicitly tell us its version if the module mod_version is not
# available. In this case, we check for the availability of module
# mod_authz_core (which should be on 2.4 or higher only) as a best guess.

forum is set up in the /forum/ folder

does anyone know what i need to change?

[karl94]

Try to add

RewriteBase /forum/

just below RewriteEngine on.

when i add that, i get the following error

Error 500

An error occurred.

This error may be due to an erroneus .htaccess file, added by you or by a script in the current directory, or by an external connection to an unreachable remote host

To check the .htaccess file you should login in your control panel, click on file management and then on the gear icon.

It's a phpBB bug, you can read more about it here: https://tracker.phpbb.com/browse/PHPBB3-14483. A temporary workaround is described here: https://www.phpbb.com/community/view...2836#p14352806.
