W3 Total Cache: Error establishing a database connection

  • 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.

    Hello Chris

    This issue should not be related to W3TC, but seems your database was not able to take the load, so crushed. Restarting the mysql server should fix it immediately but it can come again. Is your site big? In that case, you may need to have a decent server with higher memory. MySQL optimization helps a lot in situations like this.

    Have a good day!

    Cheers
    Ash
