ClosedError If this error persists, please visit the plugin settings page and enable the option named “Disable register_shutdown_function”. This could be a solution

hi i am using wp-automatic plugin for my auto news website but its now showing up this error " Error If this error persists, please visit the plugin settings page and enable the option named “Disable register_shutdown_function”. This could be a solution]"
i tried multiple methods to solve but none worked so far.
tried to increase execution time by different methods but the error still is there.
please help

it should be noted that the plugin was working like a charm for more than a week and it fetched hundreds of posts from rss feeds into my website but suddenly it stopped working
