    Though was /etc/hosts not having my host in
    127.0.0.1

    added my host and now got this:

    <!DOCTYPE html>
<html>
  <head>
    <title>200 Purged</title>
  </head>
  <body>
    <h1>Error 200 Purged</h1>
    <p>Purged</p>
    <h3>Guru Meditation:</h3>
    <p>XID: 32770</p>
    <hr>
    <p>Varnish cache server</p>
  </body>
</html>

    so what’s wrong

    <h1>Error 405 This IP is not allowed to send PURGE requests.</h1>

    I see :S

    well lets hope

    also outside topic, if you manage any medium/high traffic blogs

    take 5-10 minutes and read about varnish hector

    https://reviewsignal.com/blog/2014/06/25/40-million-hits-a-day-on-wordpress-using-a-10-vps/
    https://www.garron.me/en/linux/apache-vs-nginx-php-fpm-varnish-apc-wordpress-performance.html

    The PROS on it are huge, more if you combine it a plug in like W3TC which flushed the cache under w3tc rules its amazing what you can acomplish

    I see
    only thing that got me real confused is:

    All was fine (or semi fine) until I installed varnish, once i installed varnish, with 1/3 my peak traffic (which got me 20-30% cpu usage) I got 100% usage on cpu then crash, so thats the weird thing

    thanks tho for the help

    Thread Starter Daniel

    (@gabu69)

    Do you plan to do any mod for this? I mean some way to make it lighter in the future? For medium-high traffic it would be a pain, my site gets about 300k pageviews per day and i expect to have 3-5x by the end of the year and it would be too resource consuming :S

    Thread Starter Daniel

    (@gabu69)

    I had a server without varnish up to yesterday

    Server could handle properly with a 20-30% cpu load up to 15-30 new users per second

    After installing varnish (which should decrease my cpu and ram load by a lot)

    Once website startes getting 5-10 users per second, admin-ajax.php goes crazy high and crashes my server

    how to avoid this?

    I mean everything should be even better but now it just crashes

    Thread Starter Daniel

    (@gabu69)

    any feedback on this?

    Works

    You probably also need to change a value on your wp_options table as well. There’s an option_name called blog_charset, set its value to UTF-8. I believe that should fix it.

    It’s set as UTF-8, idk what is wrong then :S

    Thread Starter Daniel

    (@gabu69)

    Good day hector

    I tried changing my dabatabse to UTF-8 (my php characters default was already UTF8) since some tables were not UTF-8 and the error is still there

    https://bit.ly/1sv3B75

    You can notice, 3 out of 6 boxes are displayed, but the other 3 don’t show up and shows that error

    so it might be another thing?

    Thread Starter Daniel

    (@gabu69)

    thanks for the fix

    Why was this not happening before and until this last upgrade?
