If the network tab returns a HTTP 200 status, and the transfer is of several kilobytes, it's very likely this is the problem. You can check if that's the case if you open your browser console (hit F12) and reload the page. If you can see the page contents briefly, and suddenly the entire page goes blank, most likely the problem is caused by the presence of a document.write, document.writeln, or document.open JavaScript instruction in one of the scripts of the wiki. If it's the email server, check if you can connect to it from the server running MediaWiki, for example, running the Telnet client to the server and port configured on $wgSMTP and seeing if it can connect. This may be the database server, or if it happens doing a specific action, the mail server (if you have configured email settings). If the page just hangs loading during some time (like 30 seconds) doing a specific action, and then it results in a blank page or HTTP 500 error, the problem is a timeout connecting to some server. This change does not require you to restart Apache. Scan for the line containing the memory_limit setting and increase as needed.Ģ0M may not be enough if you are running version 1.15.1. The memory limit may also have been set in your LocalSettings.php file. Make sure to restart your webserver after you have changed this value. To modify this setting edit /etc/php.ini and increase the 'memory_limit' setting.įor example to raise it to 32 MB replace the existing text with memory_limit = 32M. Please check your PHP and/or Apache error logs. Many people report blank pages in recent versions after submitting articles to their new wiki.Ī likely cause is the memory limit in default php installations (usually 8 MB). The fix is to update the fault_socket entry in the php.ini file.

If LocalSettings.php is set to the correct MySQL socket but php.ini is not, it may result in a blank screen with no error output from the webserver or php. It may be necessary to refresh the cache and restart the webserver afterwards. If so, simply copy the missing files from the package into your MediaWiki directory. Check the original installation package at MediaWiki (make sure to consult the appropriate version) to see if this is the case. when the media folder in your /includes folder is no longer present, you may receive the message that a required imaging process 'failed to open stream'). Certain files may be reported as missing (e.g.You are *required* to use the date.timezone setting or the date_default_timezone_set() function.' Check if date.timezone = is set correctly (or set at all) in PHP.ini.

'Warning It is not safe to rely on the system's timezone settings.

In some cases, PHP errors might also be recorded in the web server error log.

You can also set a value for error_log in PHP.ini and read the PHP error log to find out what's going on. Error_reporting ( E_ALL ) ini_set ( 'display_errors', 1 )
