It doesn’t sound like any of you are having the same problem, unless you’re all forgetting to mention you’re running multi-site. I’d appreciate it if you started your own support threads because your issues don’t seem to be related to mine.

I’m still getting the same problem when trying to minify, however now I’m getting a more useful error message:

Minify Auto does not work properly. Try using Minify Manual instead or try another Minify cache method. You can also try a lower filename length value manually on settings page

This gives me a link to a settings page, but I then get a permission denied message. I presume this is because I’m using multi-site and the plugin is in community mode as the link directs to the W3TC settings for that particular site. Anyway, if I manually go to the Minify settings and reduce the file name length to something shorter, like 25, I still get the same error.

I think this was solved in a subsequent release so the topic can be closed. I’m just waiting for the latest update to be released to see if it solves a different minify problem I’m having now.

Support request sent 🙂

Here’s the contents of my w3tc.conf file, which is included in the configuration file for this virtual host:

Surely the issue is with the way W3TC figures out the document root of the .css and .js files it’s trying to minify though, rather than with the config file?

My bad – should have checked the error logs! The plugin consumes vast amounts of memory and my memory_limit was set too low in php.ini 🙂
