 * [@irinashl](https://wordpress.org/support/users/irinashl/) Thank you for reporting
   this quickly. You must have debug logging enabled. We added a fix to the 2.8.2
   version that is available at [https://downloads.wordpress.org/plugin/w3-total-cache.2.8.2.zip](https://downloads.wordpress.org/plugin/w3-total-cache.2.8.2.zip)
   and will be including it in the next release. You can either download and install
   the updated version or wait for the next version update.
