At his case i see this error at server logs.Got error ‘PHP message: PHP Warning: filter_input(): Unknown filter with ID 16777216this filter is about he license? * When those errors start, cpu usage is going high even at high end server, so i am deleting transients (in my case actually i flush object cache) in order to stop the bulk optimization * Any idea? * Thank you! - This topic was modified 1 year, 7 months ago by [manos2000](https://wordpress.org/support/users/manos2000/).
