Error about get_local_referer after upgrade

I have just upgraded our Moodle site from 4.0.5 to 4.3.4 and now I am getting the following error:

PHP Fatal error:  Uncaught Error: Call to undefined function get_local_referer() in /home/********.org/lib/setuplib.php:575
Stack trace:
#0 /home/*******org/lib/setuplib.php(363): get_exception_info(Object(Error))
#1 [internal function]: default_exception_handler(Object(Error))
#2 {main}
  thrown in /home/*******org/lib/setuplib.php on line 575

I performed the same upgrade to our test Moodle site on the same server, and that went without a hitch. I have done a lot of googling today, and I cannot find an answer anywhere that solves my problem.

Any help would be greatly appreciated. Our environment is like this:

  • $ uname -a
    Linux ***hostname*** 4.18.0-477.15.1.lve.2.el8.x86_64 #1 SMP Wed Aug 2 10:43:45 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

get_local_referer() is defined in lib/weblib.php, which is a fundamental library file in Moodle - see https://github.com/moodle/moodle/blob/143c2cd5bef1268751d58bbfc6c66c1d93cb9797/lib/weblib.php#L230

I would start by checking that lib/weblib.php exists and the declaration for get_local_referer is to be found at (exactly) line 230.

PHP fatal errors are thrown at a lower level than the PHP code, is at the interface between PHP and the OS. How exactly do you upgrade - following https://docs.moodle.org/403/en/Upgrading ? I ask because the upgrade script goes through a set of self-checks. If both scripts went "all green" two places come to my mind: PHP and system interactions what you find under yoursite/admin/settings.php?section=systempaths or the provider has touched some PHP setting like open_basedir or disabled PHP exec(). This is a subject for your hosting service.

I assume you've eliminated the obvious like copying new source over the old or not purging all server caches.

Is that message all you get Debugging set to maximum?

The error - Call to undefined function get_local_referer() in /home/ymcanorf/learning.ymcanorfolk.org/lib/setuplib.php:575 - is pretty clear. So either the function (or file it's in) is not there / corrupt or hasn't been loaded. The latter would imply a notice for failing to include lib/weblib.php. So, yes, upping Debugging (in config.php) is probably a good move.

Thank you so much for showing me how to turn the debugging on. I found out that the problem was in the theme, and managed to fix it.

Glad that you could SOLVE the problem.

Generally, it is helpful to leave more information like what theme, which version, it doesn't support Moodle 4.3 or there is a newer one which does, etc. There are always others who come directly to these forums through search engines.

You are absolutely right. Thank you for reminding me.

I am using the Edumy theme (2020 version, can't find the actual version number). I had to edit the theme/edumy/classes/navigation/primary.php file and change line 79 to:
 
protected function get_primary_nav($parent = null): array {
 
(add the "$parent = null" bit between the brackets). I think I am going to have to upgrade the theme before going to Moodle 4.4.
 
BTW. I cannot find a way to mark this thread as solved.

SOLVED

We just did it together.

Read "Once your problem is solved, reply to the thread, adding [Solved] to the subject line of your post and providing links to the documentation, discussion or tracker issue that helped you." in the Code of conduct.

Either way Edumy is a commercial theme outside of the moodle.org. They provide support for their products directly.
