    Hi…
    When Gzip is activated, the following code is added to .htaccess

    
    # 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/otf
    		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
    		Header append Vary User-Agent
    	</IfModule>
    </IfModule>
    # END WP-Optimize Gzip compression

    This code leads to error 500 instantly, unless removed.
    What is the issue?

    @droidafrica The rules looks good, do you have any other rules inside your .htaccess besides default WordPress rules, if yes can you please remove other rules and keep only default WordPress rules and WP-optimize rules and check if it works?

    Thanks for the reply @bornforphp
    Just to avoid back and fort communication, I have included the the other content of my .htaccess

    # BEGIN iThemes Security - Do not modify or remove this line

    # END iThemes Security - Do not modify or remove this line
    
    # BEGIN WordPress
    # The directives (lines) between "BEGIN WordPress" and "END WordPress" are
    # dynamically generated, and should only be modified via WordPress filters.
    # Any changes to the directives between these markers will be overwritten.
    <IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteRule ^index\.php$ - [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule . /index.php [L]
    </IfModule>
    
    # END WordPress

    As you can see, aside WP default, the other code in the .htaccess is generated by iTheme security plugin.
    Thanks for reviewing

    @droidafrica Can you please keep only default WordPress rules and remove iThemes rules and then try to click Gzip and check if it works?

    @droidafrica

    Could you send me a copy of your server’s Apache log?
    If you are unsure where to find the PHP Error log, you can ask your hosts to provide it.

    Can you also share your Site url?
