October CMS update error


I would like to update October CMS from 3.4.10 to 3.4.16. Locally it was successfull but in production enviroment I got the following error:

Warning : require(/home2/r56550ping/yuppicamp/vendor/composer/…/myclabs/deep-copy/src/DeepCopy/deep_copy.php): Failed to open stream: No such file or directory in /home2/r56550ping/yuppicamp/vendor/composer/autoload_real.php on line 41

Anyone has an idea what could happened?

Thank you,

Hi @ngyzsolt

The update process may have failed during the update, which can leave it in an incomplete state. There are some ways to solve this.

  • Run composer update to repair/complete the installation

  • Increase the maximum execution time in the PHP settings. It is found in your php.ini file under max_execution_time

I hope this helps.
