the message is just informational, and is omnipresent.

to turn off debugging:

in your /conf/config.php file

change

$Configuration['Debug'] = TRUE;

to

$Configuration['Debug'] = FALSE;

OR

 remove the line $Configuration['Debug'] = TRUE;

Welcome to the community!

What version number of Vanilla are you running?

Blank screens are usually indicate an error occurred while parsing the PHP script. Please enable debugging by adding $Configuration['Debug'] = TRUE; to your /conf/config.php file. This should cause an actual error screen to show up.

i have the latest version 2.1

where exactly should i add that?

under Database, EnabledApplications, Garden?

peregrine

anywhere is fine. however, its usually easier to find when you like things together. the config sorts itself out when you make a settings change in dashboard and rewrites itself anyway.

thanks for providing your error info.

it may be a result of using to restrictive a php setup or perhaps php version, e.g. safe mode or some other parameters - you might consider talking to to your host provider

http://www.php.net/manual/en/features.safe-mode.functions.php

Chalipa

php safe mode is off and i have php version 5.4.30 but still the same error

parse_ini_file has most probably been disabled (via disable_functions) in your php.ini. Some hoster give you access to that file. You can check that and - if possible - remove parse_ini_file from the list by yourself or you have to contact your web hoster to do that for you.

Your host probably thinks disabling parse_ini_file equals better security. But parse_ini_file is a parsing function, it doesn't control file permissions, so it is not better security.

That said this issue probably comes up every now then, probably work putting it in a wrapper.

...besides it is not as they can't get php settings anyway. "Cargo Cult" system admin.

write_ini_string should be enabled too.

Fatal error: Call to undefined function mb_detect_encoding() in /home/talkvp/public_html/library/vendors/simplehtmldom/simple_html_dom.php on line 988
