Drupal's JS and CSS optimization error

Question

I started getting errors after I turned on Drupal's performance improvements which pack all the CSS and JS files into single files. The error looks like this:

The selected file /tmp/fileO4fjBF could not be uploaded, because the destination js/js_8a69e612be02242c2866a4a19223bd12.js is not properly configured.

I'm not sure how I should configure my server for this to work correctly. There is nothing in the documentation about this.

Answer 1

Check you ' Site Configuration > Files' settings or the report. If it is a file permission issue (or maybe a missing folder) it should be apparent from one of those two places.

Often the report or files-settings also supply information on how to remedy the problem.
