 * Hello,
 * I have been receiving an error in WP debug:
 * PHP Notice: is_feed was called **incorrectly**. Conditional query tags do not
   work before the query is run.
 * I have narrowed this down to W3TC plugin and specically General Settings > User
   Experience > Lazy Load Images
 * With the feature unchecked I no longer get the error.
 * Is the error acceptable and can be ignored? Or best to leave it unchecked?
 * Thankyou

 * Thank you for reaching out and I am happy to assist you with this.
    Notice errors
   are minor errors. They are similar to warning errors, as they also don’t stop
   code execution. Often, the system is uncertain whether it’s an actual error or
   regular code. Can you please share which version of WP you are currently using
   and Can you also please share the website URL and the entire PHP Notice message?
   Thanks!
