I do polish translation for phpbb 3.2.0 and I don't understand what mean:
'UPLOAD_CERT_VALID' => 'Validate upload certificate',
'UPLOAD_CERT_VALID_EXPLAIN' => 'If enabled, certificates of remote uploads will be validated.
This requires the CA bundle to be defined by the <samp>openssl.cafile</samp> or <samp>curl.cainfo</samp> setting in your php.ini.',
I would like to translate it as clear as possible
