Hello,

our site is running on Moodle 4.3. It worked well but today the site won't answer. (HTTP Error 500).

I get this from the logfile

AH01071: Got error 'PHP message: PHP Fatal error:  Uncaught Error: Call to undefined function get_local_referer() in /www/htdocs/w00c56c4/moodle_bmk/moodle/lib/setuplib.php:575\nStack trace:\n#0 /www/htdocs/w00c56c4/moodle_bmk/moodle/lib/setuplib.php(363): get_exception_info(Object(Error))\n#1 [internal function]: default_exception_handler(Object(Error))\n#2 {main}\n  thrown in /www/htdocs/w00c56c4/moodle_bmk/moodle/lib/setuplib.php on line 575', referer: https://www.moodle-bmk-hh.de/course/view.php?id=1452

Is the file lib/weblib.php present in your Moodle source code folder? Does it contain the definition for get_local_referer():

    ⋮
 229  */
 230 function get_local_referer($stripquery = true) {
 231     if (isset($_SERVER['HTTP_REFERER'])) {
    ⋮

Your error is saying this cannot be found so check if it's there.

Enable debugging by adding these lines to config.php:

@error_reporting(E_ALL | E_STRICT);
@ini_set('display_errors', '1');
$CFG->debug = (E_ALL | E_STRICT);
$CFG->debugdisplay = 1;

These lines must be inserted before the last require_once(__DIR__ . '/lib/setup.php'); line. Hopefully this will show more detail with the error either in the browser or in the log file.

Please tell us your PHP version. Use a PHP info file to be certain.

These deprecation warnings are due to the SAML2 Single sign on (auth_saml2) plugin. The version on the plugins directory only supports up to Moodle 4.1. However it looks like this has been reported (#781 Deprecated: Creation of dynamic property" warnings with PHP 8.2) and the version on GitHub contains a fix for this.

However, these warnings shouldn't stop your site from working, I'd be surprised if they are linked to the original fatal error.

I wonder about that, too.
Perhaps this has something to do with it:
Last week friday I copied the moodle and the moodledata from the live server to our test domian folder "moodle4" on our server. Running with the URL (http://moodle-kp.bmk-hh.de/). Unfortuately I forgot to turn off the cronjobs in our server pointing to the testserver moodle.
So for a day the cronjob on the testserver directory was running as well as the one on the live server. Both had the same config.php and pointed to the live database.

Last saturday our live Moodle site was down and my mistake came to my attention. I turned off the cronjobs in the backend pointing to our testserver. After that the live server was back online and running. I also changed the DB-passwort in the config.php of the testserver to cut all possible connections.

The system worked fine until today and now I'm thinking that this has something to do with the actual bug...but I'm not sure.
Hope my explanation makes sense.

Has FQDN changed?

From: www.moodle-bmk-hh.de

to: student.bmk-hh.de

Or is student a SAML authentication server?

In the later .. "certpem is deprecated" - is reported.

LetsEncypt certs ok?

Have marked this thread as 'resolved'.

As to why it's working now ... suspect it had to do with cron job/task and caching as well as sessions.

But good to hear it's working again! smile
