Hi, @Olesasan . Could you please provide more context to the report issue? Where exactly do you see the error?

If it's what I'm thinking of, and you're not having any issues with your site, then it's informational and simply letting you know it's using what was cached and can be ignored. If you don't want it showing up in your logs, either update your PHP application or adjust the PHP error reporting to error only.
