[Plugin: Better WordPress Minify] Can't change cache dir

You can ignore what’s shown in the option page, as it is automatically guessed based on your minify URL. It will not affect the plugin’s functionality, don’t worry :).

This issue is marked resolved, but there actually are serious problems associated with what ksemel reported when bwp-minify is used with various common server configurations. I have only spent a short time testing, reading the code, and identifying problems, but this is what I have found so far.

bwp-minify’s path-guessing fails under Windows, works with dedicated host serving under Linux, but fails with common virtual host serving configurations under Linux. Those problems are due in part to $_SERVER[‘SUBDOMAIN_DOCUMENT_ROOT’] containing a static path set in an Apache config file, rather than a valid path to an individual virtual host document root. There also is a malfunction associated with the use of @parse_url($minurl) that I haven’t fully-determined yet.

Additionally the default empty string setting of $min_documentRoot in the min config.php is not valid with virtual host web serving, because it causes $_SERVER[‘DOCUMENT_ROOT’] to be used, which isn’t reliable for the reason explained above. The solution is to set $min_documentRoot as shown below, which I have found works reliably with both dedicated and virtual hosting under both Windows and Linux:

$min_documentRoot = substr($_SERVER['SCRIPT_FILENAME'], 0, -strlen($_SERVER['SCRIPT_NAME']));

After making the post above I discovered that min also uses $_SERVER[‘DOCUMENT_ROOT’] in several other places. Because of that, it appears to me that min will fail to work correctly with a significant percentage of web servers unless its code is patched in several places.

I am running a webserver at port 8443 with SSL…
The Plugin does not work with this settings. When calling my WP installation (https://example.tld/) the plugin is trying to call https://example.tld/wp-content/plugins/bwp-minify/min/?f=:8443/wp-content/*
Also its trying to set the cachedir to <htdocs>/:8443/wp-content/plugins/bwp-minify/cache and fails to detect its own location in <htdocs>/wp-content/plugins/bwp-minify/cache

In other words – This plugin (as of now) is not working with our installation and the page gets messed up because no CSS and JS files are loaded.

Sorry – The WP Installation is running at https://example.tld:8443 and the plugin is trying to call https://example.tld:8443/wp-content/plugins/bwp-minify/min/?f=:8443/wp-content/*

@admintiger: The codes you found inside bwp-minify only try to guess the cache dir to *show* it to the user, with no intention of using it for min application to be exact, so it’s not important that it is guessed correctly :). Regarding DOCUMENT_ROOT, it is something that should be configured differently on each user’s web server, that’s why I provide an easy way to move the min folder to another place of choice, and then you can play with the config file without worrying about the plugin’s update. I will write a short tutorial soon on how to make the most our of the min URL feature of BWP Minify.

@coksnuss: that bug has been fixed in 1.2.0, which will be released this week.
