https://tools.pingdom.com/?url=morrispaint.com&treeview=0&column=objectID&order=1&type=0&save=false

sort by “load order” may help in finding the right order to solve dependencies.

of cause you have a LOT of scripts – that doesnt make it easier..

good luck solving the puzzle!

congrats! looks much better now!

PROOF:

my page before (no minify & gzip):

after the FIX:

you may try THIS

i made a simple HowTo of kw2′s FIX here:

https://www.ads-software.com/support/topic/plugin-w3-total-cache-how-i-got-my-w3tc-working-with-minify-gzip

ADDENDUM:

for that your js scripts & css can be combined & minified steps in a certain order are appropriate:

I.
Performance->Browser Cache->Cascading Style Sheets & JavaScript: Enable HTTP (gzip) compression OFF
all Minify Setting ON, of cause.

II.
put add your css and js under minify (minify manual in general settings)
(allow updating .htaccess – you may lose changes you did for the FIX)
test of the js loading order is correct & everything works on your site.
combine js scripts & combine css.

Check with https://webpagetest.org!

your site should be optimized in W3TC by now as much as possible, just lacking proper gzip compression.

III.
the above FIX is to be applied last, when you dont want to touch W3TC settings any more..

hope this helped ??

i made a short HowTo re-post here:

https://www.ads-software.com/support/topic/plugin-w3-total-cache-how-i-got-my-w3tc-working-with-minify-gzip

@ kw2
since your fix for apache REALLY WORKS this change to gz sounds reasonable.

@sysopsavant

but it looks NOT highly optimized 75/100 score

https://www.webpagetest.org/result/110519_2A_MXP8/1/performance_optimization/

also here only 75/100 score
https://www.webpagetest.org/result/110519_8Y_MXR8/1/performance_optimization/

are you shure minify is on & properly configured?

@kw2

Vielen, vielen Dank! Super!

it works!
it works!

Howto correct Minify&Gzip-errors with W3Total Cache W3TC 0.9.2.1
(based on M. Nieberg′s
https://kenntwas.de/2011/tips/tools-allgemein/english-version-wordpress-get-w3tc-0-9-2-1-running-with-minify-and-gzip-compression/)

*** make backups of:

wp-content/plugins/w3-total-cache/lib/Minify/Minify/Controller/Base.php
    wp-content/w3tc/min/.htaccess
    root/.htaccess

*** edit wp-content/plugins/w3-total-cache/lib/Minify/Minify/Controller/Base.php

change  ,'encodeMethod' => 'zero'
to      ,'encodeMethod' => 'gzip'   //MN: Was 'zero', set to gzip

*** set in admin Performance->Minify->General: Rewrite URL structure ON

*** set in admin Performance->Browser Cache->Cascading Style Sheets & JavaScript: Enable HTTP (gzip) compression ON
 (this updates to your root/.htaccess)

*** edit wp-content/w3tc/min/.htaccess:
(in "W3TC Minify core" part)

change  RewriteRule ^w3tc_rewrite_test$ index.php?w3tc_rewrite_test=1 [L]
to      RewriteRule ^w3tc_rewrite_test$ index.php?w3tc_rewrite_test=1 [QSA,L]

add     ReWriteCond %{REQUEST_FILENAME} !^.+\.gzip$
after   RewriteCond %{HTTP:Accept-Encoding} gzip 

change  RewriteRule (.*) $1%{ENV:APPEND_EXT} [L]
to      RewriteRule (.*) $1%{ENV:APPEND_EXT} [QSA,L]

change  RewriteRule (.*) index.php?file=$1 [L]
to      RewriteRule (.*) index.php?file=$1 [QSA,L]

*** edit root/.htaccess:

remove a lot (60?) of linefeds which W3TC put.

(in "W3TC Page Cache core" part)
change  RewriteRule ^(.*\/)?w3tc_rewrite_test$ $1?w3tc_rewrite_test=1 [L]
to      RewriteRule ^(.*\/)?w3tc_rewrite_test$ $1?w3tc_rewrite_test=1 [QSA,L]

("BLOGSUB/" is the name of your WP subdirectory, is missing if installed in root)
change
RewriteRule .* "/BLOGSUB/wp-content/w3tc/pgcache/%{REQUEST_URI}/_index%{ENV:W3TC_UA}%{ENV:W3TC_REF}%{ENV:W3TC_SSL}.html%{ENV:W3TC_ENC}" [L]
to
RewriteRule .* "/BLOGSUB/wp-content/w3tc/pgcache/%{REQUEST_URI}/_index%{ENV:W3TC_UA}%{ENV:W3TC_REF}%{ENV:W3TC_SSL}.html%{ENV:W3TC_ENC}" [QSA,L]

*** make both .htaccess files writeprotected by ftp:

delete the write flags
(doesnt work for me - i only get it down to 644 not 444)

after i look in admin Performance, i got the two fleshy bars:
Disk enhanced page caching is not active..auto install
Minify is not active..auto install

.. but i ignore them because my site works!

minify & gzip is ok now!

i know the changes will be overwritten if i change my W3TC settings again.

@arundel69

glad to hear that!

just found.

for the technical minded (& fit in german) here seems to be the perfect fix:

i ll try it as soon as i have more time – dont want to break my baby ??
