Causes white screen along with Autoptimize plugin CSS optimization

@qbey,

Thanks for the update and that info. We were able to reproduce it using the RU version of WordPress.

It turns out that our translated strings are too long for a preg_replace_callback function that Autoptimize uses when optimizing comments and that causes the entire page content to return NULL which is why it’s blank for you. This is definitely a limitation within the Autoptimize plugin, but we are hoping to find a way to fix it on our end if possible.

With that in mind, until a fix is available I’ve prepared a quick code snippet you can add to your functions.php file (or using a plugin like WPCode):

add_action( 'wp_print_footer_scripts', function() {
	if ( is_admin() ) {
		return;
	}

	wp_deregister_script( 'aioseo/js/src/vue/standalone/app/main.js' );
}, '9.5' );

This isn’t a great permanent solution because it disables our translations on the front end of the site in the SEO Preview module.

We have a few ideas for how we can fix it from our end, but we also plan to reach out to the Autoptimize team to see if they can adjust the way they process the data on their end so this issue doesn’t occur in the future with any other plugins.

Thanks again for reporting this and we’ll reach out as soon as we have a permanent solution!
