    Hello and thanks for hearing me out.

    I tried to improve our Google Page Speed by editing W3 Total Cache.

    What i did:

    Set W3 Total Cache header on HTML, JS and Media.
    Expires header lifetime: 3600 seconds on HTML
    Expires header lifetime: 31 536 000 seconds on JS
    Expires header lifetime: 31 536 000 seconds on Media

    After that I emptied all the caches on disc and refreshed the website. This resulted in Error establishing a database connection.

    The issue is solved now but I want to know if those changes could have caused the problem?

    All the best,
    Chris.
