W3TC Minify problem

[Valeyard]

Hi,

I have been using w3tc to minify my css files. The minified css file has a path like /wp-content/cache/minify/000000/42376/default.include.98e853.css Recently BPS has been throwing 403 when accessing these files.

Thanks,
Edward

So where are you unning a Pingdom test on your website?  Are you seeing any other similar minify errors from other sources?  Why would this URI be accessed directly?  That seems very strange.

[Valeyard]

Yes, this also happens when I  try to access my website from my own computer. This URI is accessed because it is the combined css file used in my site?

[Valeyard]

Basically w3tc will combine all the css files used into one file and add something like this to the head

<link rel="stylesheet" type="text/css" href="http://xxxxx/wp-content/cache/minify/000000/42376/default.include.98e853.css" media="all">

I avoid minifying like the plague (problems, more problems and then lots more problems) so I am no expert on all the problems that occur when minifying things.  Personally I do not recommend that you minify anything, but each to his/her own. No one has ever reported this before and I really have no logical idea why this is occurring.  You can add a RewriteEngine Off .htaccess file in the /wp-content/cache/minify/ folder so that BPS will no longer look at these files.  See the link below.

[Valeyard]

Cool. My guess would be the wacky URI is triggering some rewrite rule for preventing attacks. For the RewriteEngine Off .htaccess, it also applies to all the subdirectories as well?

[AITpro Admin]

Uh minifying is whacky in itself.  LOL

Yep, .htaccess files are recursive/hierarchical.  An .htaccess file in a parent folder will apply its rules to the child folders of that parent, unless the child folder has its own .htaccess file.
Parent – /wp-content/cache/minify/.htaccess
Child/subfolders – /000000/42376/

[Valeyard]

Thanks! It seems the rewrite off doesn’t work, as w3tc itself uses rewriteengine to link: http: //xxxxx/wp-content/cache/minify/000000/42376/default.include.98e853.css to something like http: //xxxxx/wp-content/plugin/w3tc/minify.php?file=default.include.98e853.css After some manual testing, it seems for some reason that I don’t understand

RedirectMatch 403 /\..*$ is too general and changing it to
RedirectMatch 403 ^/\..*$ solves the problem.

Btw, I have some apache error msgs regarding /404.php not found (the theme’s 404 page does show up tho), I think a better way to do it is change: ErrorDocument 404 /404.php to ErrorDocument 404 /index.php?error=404 according to http://codex.wordpress.org/Creating_an_Error_404_Page#Help_Your_Server_Find_the_404_Page

[AITpro Admin]

Not sure why adding a caret would work for the RedirectMatch 403 code.  That code only matches files that start with a dot.  Example:  .htaccess, .htpasswd, etc. using index.php?error=404 ONLY works if you are not using a Custom Permalink Structure.

[Valeyard]

Ahh I see. Changed the 404 thing back. Thanks again for the help.

The most logical thing to try first would be a skip/bypass rule for the W3TC cache folder.

1. Copy this code below to this BPS Custom Code text box:  CUSTOM CODE PLUGIN/THEME SKIP/BYPASS RULES: Add personal plugin/theme skip/bypass rules here  
2. Click the Save Root Custom Code button.
3. Go to the BPS Security Modes page and click the Root Folder BulletProof Mode Activate button.
Note: If your WordPress installation/website is in a folder named /MyWordPressFolderName/ then add your WordPress folder name in the path: example: RewriteCond %{REQUEST_URI} ^/MyWordPressFolderName/wp-content/cache/minify/ [NC]

# W3TC Minify skip/bypass rule
RewriteCond %{REQUEST_URI} ^/wp-content/cache/minify/ [NC]
RewriteRule . - [S=13]

If the code above does not work then try this next…

# W3TC Minify skip/bypass rule
RewriteCond %{REQUEST_URI} ^/wp-content/cache/minify/(.*)\.js [NC]
RewriteRule . - [S=13]
