 * I’m noticing that when I save a page in the backend or even when I access it 
   to edit it, I get the following error: Fatal error: unknown: can not use output
   buffering in output buffering display handlers in unknown on line 0. I think 
   that’s what the minify setting is for . When I clean the cache I finally edit
   the page. Are you aware of this error? Use wp 4.9 and jupiter theme 6

 * This might have something to do with the not enough memory. Could you increase
   the maximum allowed by adding this to your `wp-config.php` file:
    `define( ‘WP_MEMORY_LIMIT’,‘
   512M’ );`
 * If it doesn’t work, please change `define('WP_DEBUG', false);` to `define('WP_DEBUG',
   true);` and see if there is any error showing when you try to edit the page.
