I'm using both W3 Total Cache and BackWPup.
I receive the following warning in BackWPup:
WARNING: File name "wp-content/cache/minify/000000/XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX.css.gzip" too long to be saved correctly in TarBz2 archive!
This seems to be due to the length of the filename that's generated by W3, correct?
How do I set the filename length to a lower value? I see mention of it in the 'Minify' section, but the value is un-editable.
Any ideas? (This is happening for only my CSS and JS files.)
