See the following: * DeflateFilterNote (mod_deflate.c) DeflateWindowSize (mod_deflate.c) DeflateBufferSize( mod_deflate.c) DeflateMemLevel (mod_deflate.c) DeflateCompressionLevel (mod_deflate. c)” * I dont know what to do now.

The file should be named .htaccess. But I guess it’s just a typo… * The lines that you have in your .htaccess file will only be valid if your server type is Apache. When I tried to query your server, I did not get the server type in the response. That is strange. Perhaps, your host is hiding it. So the first thing I would do is contact the host and ask the following questions: 1. What web server is your site running on? 2. Do they have Nginx working together with Apache? * Depending on their response, we can continue on debugging your issue. * Another easy thing you can try – do a small test and see if the directives in your .htaccess file are being parsed by the server. * Here’s how it’s done: 1. Open up your .htaccess file in any FTP editor (not with WordPress) 2. Right after write in any word or sequence of letters/numbers. For example, 123 3. Save the file. Refresh your website in the browser. If you are getting a weird error, that means the lines have been parsed by the web server. That’s good news. Yes, if you get an error with this test – it’s good news ) 4. Remove the added text from the .htaccess file. Save it. Your site is back to normal. Don’t forget to remove the added text even if there was no error. * Will wait for the info, regarding your server type and if the .htaccess test yielded an error or not. * Best regards, Anton * Thread Starter [bradburyarchitecture](https://wordpress.org/support/users/bradburyarchitecture/) * (@bradburyarchitecture) * [8 years ago](https://wordpress.org/support/topic/mod_deflate/#post-10222533) * [@vanyukov](https://wordpress.org/support/users/vanyukov/) * Hi Anton, Not sure if I reply through here or the email so I will try both. * Yes it was a typo on my side. * the test: This is what is showing on my side and where i added the 123 * DirectoryIndex index.php * # BEGIN WordPress RewriteEngine On RewriteBase / RewriteRule ^index\.php$ – [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME}!- d RewriteRule . /index.php [L] * # END WordPress # BEGIN WP-HUMMINGBIRD-GZIP * SetOutputFilter DEFLATE < IfModule mod_headers.c> SetEnvIfNoCase ^(Accept-EncodXng|X-cept-Encoding|X{15} |~{15}|-{15})$ ^((gzip|deflate)\s*,?\s*)+|[X~-]{4,13}$ HAVE_Accept-Encoding RequestHeader append Accept-Encoding “gzip,deflate” env=HAVE_Accept-Encoding ** 123** AddOutputFilterByType DEFLATE “application/ atom+xml” \ “application/javascript” \ “application/json” \ “application/ld+json”\“ application/manifest+json” \ “application/rdf+xml” \ “application/rss+xml” \ “ application/schema+json” \ “application/vnd.geo+json” \ “application/vnd.ms-fontobject”\“ application/x-font-ttf” \ “application/x-font-opentype” \ “application/x-font- truetype” \ “application/x-javascript” \ “application/x-web-app-manifest+json”\“ application/xhtml+xml” \ “application/xml” \ “font/eot” \ “font/opentype” \ “ font/otf” \ “image/bmp” \ “image/svg+xml” \ “image/vnd.microsoft.icon” \ “image/ x-icon” \ “text/cache-manifest” \ “text/css” \ “text/html” \ “text/javascript”\“ text/plain” \ “text/vcard” \ “text/vnd.rim.location.xloc” \ “text/vtt” \ “text/ x-component” \ “text/x-cross-domain-policy” \ “text/xml” * AddEncoding gzip svgz * # END WP-HUMMINGBIRD-GZIP AddHandler phpCGI .php Action phpCGI / cgi-bin/php5-cgi * # BEGIN WP-HUMMINGBIRD-CACHING * ExpiresActive On ExpiresDefault A0 * ExpiresDefault A691200 * ExpiresDefault A691200 * ExpiresDefault A691200 * ExpiresDefault A691200 * Header set Cache-Control“ max-age=691200” * Header set Cache-Control “max-age=691200” * Header set Cache-Control “max-age=691200” * Header set Cache-Control “max- age=691200” # END WP-HUMMINGBIRD-CACHING * No error occurred on the site. * Answering your questions from our host: 1.

Can you please ask your host if it’s possible to install or activate that module for your site? Once that is done, try that test with the error again. If you get the error, compression on your site should start working. * If host won’t install/activate that module, we’ll find a workaround. * Best regards, Anton * Plugin Support [Dimitris – WPMU DEV Support](https://wordpress.org/support/users/wpmudev-support6/) * (@wpmudev-support6) * [8 years ago](https://wordpress.org/support/topic/mod_deflate/#post-10270182) * Hello [@bradburyarchitecture](https://wordpress.org/support/users/bradburyarchitecture/) * It’s been a while since we’ve header back from you, so I’m marking this topic as resolved.
