Changing PHP-FPM flag editor (options list) and compiling again

Hello

I am trying to select IMAGIC and recompile PHP-FPM 7.2 but adding ticks to items and pressing back button on the page has no effect. Next time you visit the page, everything is as if you did not change anything.

How can I use this page to enable Imagic module and recompile the php 7.2?

Thanks.

Try to press the save button before the back button
