I'm trying to install phpBB-3.0.0 but I get this at the 'Installation compatibility' step.
PHP version and settings
Required - You must be running at least version 4.3.3 of PHP in order to install phpBB. If safe mode is displayed below your PHP installation is running in that mode. This will impose limitations on remote administration and similar features.
PHP version >= 4.3.3:Yes
PHP setting register_globals is disabled: No
phpBB will still run if this setting is enabled, but if possible, it is recommended that register_globals is disabled on your PHP install for security reasons.
PHP setting allow_url_fopen is enabled: Yes
Optional - This setting is optional, however certain phpBB functions like off-site avatars will not work properly without it.
PHP function getimagesize() is available: Yes
Required - In order for phpBB to function correctly, the getimagesize function needs to be available.
PCRE UTF-8 support: Yes
phpBB will not run if your PHP installation is not compiled with UTF-8 support in the PCRE extension.
mbstring extension check
Required - mbstring is a PHP extension that provides multibyte string functions. Certain features of mbstring are not compatible with phpBB and must be disabled.
Function overloading: Yes
mbstring.func_overload must be set to either 0 or 4.
Transparent character encoding: Yes
mbstring.encoding_translation must be set to 0.
HTTP input character conversion: No
mbstring.http_input must be set to pass.
HTTP output character conversion: No
mbstring.http_output must be set to pass.
How can I solve this? thanks
