Recently an error occurred while creating the CSS / JS minify cache: No sources

WP 4.1 here as well,
W3TC version 0.9.4.1

Same issue. Any solutions?

Me too
Same WP 4.1 and W3TC 0.9.4.1

Me too. I have WP 4.1.1 and W3TC version 0.9.4.1.

Same here. After deactivating/reactivating JS and CSS minify, the error is now File ".../public_html/wp-content/plugins/js_composer/assets/css/js_composer_front.css" doesn't exist.

That file doesn’t exist in ages in that plugin. I read several articles regarding the problems W3TC can create, but I didn’t know it can crash an entire server. Until now, that is. ??

Still no solution for this?
