Hi,

We have had a problem with 500 error code in our servers. 


[18-Jul-2021 17:01:45 Europe/Madrid] PHP Fatal error:  Uncaught Error: Call to undefined function current_language() in /html/lib/setuplib.ph

Stack trace:

#0 /html/lib/setuplib.php(560): get_docs_url()

#1 /html/lib/setuplib.php(351): get_exception_info(Object(ParseError))

#2 [internal function]: default_exception_handler(Object(ParseError))

#3 {main}

  thrown in /html/lib/setuplib.php on line 701

[18-Jul-2021 17:01:48 Europe/Madrid] PHP Fatal error:  Uncaught Error: Call to undefined function current_language() in /html/lib/setuplib.php

The version of our php is 7.2.24

At the end we have recovered the services by cleaning cache directories:

  • cache
  • trashdir
  • temp

Someone with the same problem could explain why we have fixed the problem by remove those directories?

Thanks in advance

Israel Forés.

Picture of Core developers Picture of Particularly helpful Moodlers

What version of Moodle is this? There was a bug in 3.7 and earlier, MDL-65996, where an error early on in Moodle's initialisation could lead to this unrelated message because of a bug in Moodle's error handling.

So if you do have Moodle 3.7 or earlier then you should upgrade.

But if you have a currently supported Moodle version and this problem happens again then you may need to comment out the calls to get_docs_url() and debugging() as described in MDL-65996's description to see to root cause.

Hello Leon,

Sorry I forgot to notify the moodle version. Our version is 3.5, I'm going to check MDL-65996.

Thanks for the info. I haven't find this info in my research, I only find info about the php version.

Thanks again and have a good day
