# PHP Warning: Undefined array key “defaultState” in BlockCss.php

 * Without any recent changes, I suddenly started seeing this warning in the logs:
 * `PHP Warning: Undefined array key "defaultState" in /plugins/athemes-blocks/includes/
   Blocks/BlockCss.php on line 157`
 * I don’t notice any issues on the site itself, but the warning keeps appearing
   in the error logs.
   Is there a fix or update planned for this?

 * Hi [@t3sterk](https://wordpress.org/support/users/t3sterk/),
   I’m having some 
   trouble reproducing this warning on my end too.To ensure that I’m using a similar
   environment, could you please go to **WordPress > Tools > Site Health > Info 
   > Copy to clipboard** and share the site info in your next reply so that I can
   set up a similar environment? Feel free to reduct any sensitive information such
   as the site paths.Thank you!
