wiki.transitionnetwork.org displaying error

[chris]

This is rather weird, the site was working yesterday, now at ​https://wiki.transitionnetwork.org/ we have:

bar(), etc etc) which throw parse errors in # PHP 4. Setup.php and ObjectCache.php have structures invalid in PHP 5.0 and # 5.1, respectively. if ( !function_exists( 'version_compare' ) || version_compare( phpversion(), '5.3.2' ) < 0 ) { // We need to use dirname( __FILE__ ) here cause __DIR__ is PHP5.3+ require dirname( __FILE__ ) . '/includes/PHPVersionError.php'; wfPHPVersionError( 'index.php' ); } require __DIR__ . '/includes/WebStart.php'; $mediaWiki = new MediaWiki(); $mediaWiki->run();

We are not the first people with this error:

• ​http://serverfault.com/questions/594708/mediawiki-does-not-run-for-the-first-time

The page being displayed is the index.php file as plain text, this is the content of the file:

# Bail on old versions of PHP.  Pretty much every other file in the codebase
# has structures (try/catch, foo()->bar(), etc etc) which throw parse errors in
# PHP 4. Setup.php and ObjectCache.php have structures invalid in PHP 5.0 and
# 5.1, respectively.
if ( !function_exists( 'version_compare' ) || version_compare( phpversion(), '5.3.2' ) < 0 ) {
        // We need to use dirname( __FILE__ ) here cause __DIR__ is PHP5.3+
        require dirname( __FILE__ ) . '/includes/PHPVersionError.php';
        wfPHPVersionError( 'index.php' );
}

require __DIR__ . '/includes/WebStart.php';

$mediaWiki = new MediaWiki();
$mediaWiki->run();

So it looks like a Nginx config issue. Some changes were made yesterday to enable large files to be uploaded on ticket:719.

Also this line in /etc/nginx/sites-enabled/10-wiki:

        #location ~ /(api|index|opensearch_desc|redirect|trackback|img_auth|load|thumb)\.php?$ {
        location ~ /(api|img_auth|index|load|opensearch_desc|profileinfo|thumb|thumb_handler?)$ {

Was edited. the old version being commented out, as it had started generating errors yesterday, the closing ) bracket was added.

Don't think this was related to a Nginx upgrade, the last one was 3 weeks ago, ticket:692#comment:51

Edited the above to:

        # Pass php requests to php5-fpm
        # https://tech.transitionnetwork.org/trac/ticket/753
        #location ~ /(api|index|opensearch_desc|redirect|trackback|img_auth|load|thumb)\.php?$ {
        location ~ /(api|img_auth|index|load|opensearch_desc|profileinfo|thumb|thumb_handler)\.php$ {

I think the mistake in the regular expression must have crept in when trying to resolve the problems with the last MediaWiki upgrade, ticket:736, it's now resolved.
