Nothing is working as expected. NOTHING.
And as soon as you have spent days of you life digging in the code, he changes something and: the actual file resides in wp-content/cache/minify/000000/34c4b/default.include.js but browser requests /wp-content/cache/minify/000000/34c4b/default.include.4b1194.css
Congratulations! You are served. Another heart atack and another day went for nothing. [abusive comment removed]
