When running the One Click Update on a new installation of ExpressionEngine 5.2.3, the update fails with the following messages:

We stopped on Updating files.

Log file path not writable:[Server path]\system/user/cache/ee_update

The error message also provided the stack trace below. The full server path has been replaced with [Server path].

#0 [Server path]\system\ee\updater\EllisLab\ExpressionEngine\Updater\Service\Updater\Runner.php(351): EllisLab\ExpressionEngine\Updater\Service\Logger\File->__construct(‘[Server path]…’, Object(EllisLab\ExpressionEngine\Updater\Library\Filesystem\Filesystem), false)

ExpressionEngine is installed on a server running Windows Server 2016 with Apache 2.4, PHP 7 and MySQL 8. The system is installed and appears to be working normally except for this update error. This is a new installation, and I have not been able to previously run the updater successfully.

I can confirm that ExpressionEngine is able to write to the \system\user\cache directory in two ways:

  • The updater is able to create the ee_update directory within the cache directory and successfully download and write the following directories and files:

    • ExpressionEngine (dir)
    • configs.json
    • ExpressionEngine.zip
    • index.html
    • update.txt
  • Also, I am able to run and successfully complete the Database Backup Utility from the Control Panel, which results in a SQL text file written to \system\user\cache.

While the error code clearly points to a permissions issue, my understanding is that default installations of Apache on Windows Server run under the System account, which has full permissions to the \system\user\cache directory.

I confirmed that PHP is running as the System account by running the following statement:

<?php echo exec('whoami'); ?>

I wondered if differences in the use of \ and / to separate file paths in UNIX and Windows might be an issue, but I am able to navigate to the [Server path]\system/user/cache/ee_update directory given by the update error message from the command line.

Any ideas for troubleshooting or a fix for this issue? Any guidance would be a huge help! Thank you!

  • Might be worth checking with the Ellis Labs bods about use of MySQL 8. Others have reported issues when using it (for example, here - expressionengine.com/forums/topic/252210/… ) – JCOGS Design Jun 28 '19 at 11:23
  • Thanks for the great idea! I was aware of Robin Sowell's post last fall on MySQL 8 and ExpressionEngine compatibility and handled that when I set up the MySQL 8 installation. Just confirmed on the server that it is using the mysql_native_password format for the default_authentication_plugin. Since the rest of ExpressionEngine is functioning normally (Control Panel access, logins, etc.), the problem may be elsewhere. Thanks for taking time to eliminate another possible source of error! – RDW Jun 28 '19 at 21:46
