(This article has been tested on Debian, but should also apply to other installations with confixx.)
On servers that use the administrative tool Confixx, you cannot edit apache´s php.ini directly. But you can edit php.ini for php´s cli.
In confixx you create the required php settings in httpd special.
Confixx specifics:
You have to expand the include_path by adding the VIMP installation folder, its 'lib/symfony/vendor' and 'lib/symfony/plugins/sfPropelPlugin/lib/vendor' folders.
The reason for this is that settings with php_admin_value or php_admin_flag can´t be overwritten by scripts, but VIMP does. confixx uses php_admin_value for its vhost settings. The symfony framework (exact propel) expands the include path by using set_include_path() to add its folders.
An example how the httpd special entry should look (customize web0 and MYDOMAIN.TLD):
DocumentRoot /home/www/web0/html/MYDOMAIN.TLD/web php_admin_flag safe_mode off php_admin_flag register_globals off php_admin_flag allow_url_fopen on php_admin_value post_max_size 2047M php_admin_value upload_max_filesize 2047M php_admin_value memory_limit 512M php_admin_value include_path '.:/home/www/web0/html/MYDOMAIN.TLD:/home/www/web0/html/MYDOMAIN.TLD/lib/symfony/plugins/sfPropelPlugin/lib/vendor:/home/www/web0/html/MYDOMAIN.TLD/lib/symfony/vendor'
