Gzip compression added without notice

Our podcast, which is broadcast to hundreds of radio stations around the world, went down when re-activating the latest version of WP-Optimize. The culprit, I discovered, was the following lines in .htaccess, which affected XML files:

# BEGIN WP-Optimize Gzip compression
<IfModule mod_filter.c>
	<IfModule mod_deflate.c>
# Compress HTML, CSS, JavaScript, Text, XML and fonts
		AddType application/vnd.ms-fontobject .eot
		AddType font/ttf .ttf
		AddType font/otf .otf
		AddType font/x-woff .woff
		AddType image/svg+xml .svg
		
		AddOutputFilterByType DEFLATE application/javascript
		AddOutputFilterByType DEFLATE application/rss+xml
		AddOutputFilterByType DEFLATE application/vnd.ms-fontobject
		AddOutputFilterByType DEFLATE application/x-font
		AddOutputFilterByType DEFLATE application/x-font-opentype
		AddOutputFilterByType DEFLATE application/x-font-otf
		AddOutputFilterByType DEFLATE application/x-font-truetype
		AddOutputFilterByType DEFLATE application/x-font-ttf
		AddOutputFilterByType DEFLATE application/x-font-woff
		AddOutputFilterByType DEFLATE application/x-javascript
		AddOutputFilterByType DEFLATE application/xhtml+xml
		AddOutputFilterByType DEFLATE application/xml
		AddOutputFilterByType DEFLATE font/opentype

		AddOutputFilterByType DEFLATE font/ttf
		AddOutputFilterByType DEFLATE font/woff
		AddOutputFilterByType DEFLATE image/svg+xml
		AddOutputFilterByType DEFLATE image/x-icon
		AddOutputFilterByType DEFLATE text/css
		AddOutputFilterByType DEFLATE text/html
		AddOutputFilterByType DEFLATE text/javascript
		AddOutputFilterByType DEFLATE text/plain
		AddOutputFilterByType DEFLATE text/xml
		
# Remove browser bugs (only needed for really old browsers)
		BrowserMatch ^Mozilla/4 gzip-only-text/html
		BrowserMatch ^Mozilla/4\.0[678] no-gzip
		BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
		<IfModule mod_headers.c>
			Header append Vary User-Agent
		</IfModule>
	</IfModule>
</IfModule>
# END WP-Optimize Gzip compression

There was also an issue with the settings page, because it said it was DISABLED but in fact it was enabled: https://a.cl.ly/jkuXz470

I never enabled Gzip compression here (we’re using Cloudflare).

Deleting the plugin, reinstalling, and then clicking Disable on the settings page fixed the issue (and the settings page). But please don’t ever add lines to .htaccess files without permission.

P.S. It was also very annoying that you enabled the image compression meta-box automatically. I had to disable that manually on dozens of sites.
