Moodle Error Code missingconfigversion | Troubleshooting Tips

If you have been running into the “missingconfigversion” error while upgrading your Moodle instance, you have come to the right place.

Today, our experts are going to take us through the potential causes of this issue and how to resolve the error.

Potential Causes

1. If we have recently upgraded Moodle, there is a chance that the process was interrupted, leaving configuration files incomplete. This can lead to the “missingconfigversion” error.
2. A mismatch between the Moodle code version and the version mentioned in the configuration files can cause the error.

Troubleshooting Tips

1. Check Configuration Files:
   • To begin with, head to the Moodle installation directory on the server.</li?
   • Then, locate and open the config.php file.
   • Finally, verify the $CFG->version line to make sure it matches the installed Moodle version.
2. Correct Version Information:

   Next, make sure the version in $CFG->version is in the correct format and matches the Moodle release.
3. Verify File Integrity:
   • First, we have to check the file integrity by comparing it with a clean installation of the same Moodle version.
   • Additionally, we can replace a corrupted config.php file from a backup or fresh installation.
4. Clear Cache:

   Next, manually clear the Moodle cache by deleting contents in the moodledata/cache directory to implement changes made to configuration files.
5. Upgrade Moodle:

   Furthermore, we can rerun the upgrade process if the error occurred during an upgrade. Remember to back up Moodle data and database before making changes.
6. Manual Configuration Check:

   Additionally, manually review configuration files to ensure all required settings are properly configured.
7. Check Moodle Logs:

   Then, review Moodle logs for additional error messages or information related to the “missingconfigversion” error.
8. Update Configuration Version:

   In some cases, we have to manually update the version in Moodle configuration files to align with the Moodle code version.

If none of the above tips helped, our experts recommend reinstalling Moodle.
