Fatal error: Uncaught exception 'RuntimeException' with message 'Unable to create the cache directory...'

Resolved

Reported for: WPML Multilingual CMS 3.6.1

Resolved in: 3.6.2

Overview of the issue

On some server configurations, WPML is not allowed to create a cache directory even though the permissions should allow to. This issue has been reported for IIS/8.5 server so far.

Workaround

We are still investigating this issue. In the meantime, we can suggest two alternatives:

  1. Make sure the web server is allowed to write in the wp-content directory.
  2. Define a specific “cache” directory in the wp-config.php file like the following:
    define( 'WPML_CACHE_PATH_ROOT', '/absolute/path/to/cache/folder/' );
    Where ‘/absolute/path/to/cache/folder/’ is the absolute path to your cache directory which should be writable by the web server.

  3. Similar issue here. Error message is below. Our hosting provider does not allow writing files with PHP extension to cache directory for security reasons.

  4. I have a specific error that relates to the Buddy Press integration plugin. I updated the WordPress core and WPML at the same time, would this be the issue?

    • We released just now a beta for WPML that allows it to work with WPEngine restrictions. We’ll update the texts in this errata in a few minutes. You should go to your WPML account, click on Downloads and get the Beta package. Unzip it and use the WPML components from there. This will go out as the production version on Monday.

  5. We are also experiencing this issue on a WP Engine install. We can not recreate this issue as of yet but to be sure, we have been resetting the file permissions from the Utilities menu item underneath the install name.

    • We have also contacted WP Engine support and they said:

      “Our Security App Amour is there so that a binary php cannot create another binary php. That is an exploit within itself.”

      They are essentially saying that another PHP file can’t create another PHP file which is what the plugin is attempting to do.

      Contrary to that however, is the fact that the twig file is actually being created as I’ve FTP’d the server and can browse to it. I am unable to download the file due to a Read permission…

      • It’s fine. We are not asking WPEngine to make any change in their system. We released just now a beta for WPML that allows it to work with WPEngine restrictions. We’ll update the texts in this errata in a few minutes. You should go to your WPML account, click on Downloads and get the Beta package. Unzip it and use the WPML components from there.

  7. Sorry for this hassle. We didn’t anticipate the access restriction and we did our very best to release an update as soon as we could. WPML 3.6.2 was just released. It should fix the problem for you. Can you update and see?
