Hello,
We are running a magento 2.3.3 site on a dedicated server.
we recently were running a recompile and out of the blue had some strange ash output, shortly after all our pages on our site except our homepage Yhad a 404 error.

We checked the htaccess file in the root folder and compared the file with another staging sever file.

there seemed to be a comment in that file
php_flag opcache.enable Off

we don’t know how it got there?.
Can anyone help to advise how this could be added in here, can this appear automatically or somehow generate on its own?

we then removed this comment and recompiled again without any output errors in the ssh and the site started running normally.
