    Hi,

    It’s been twice after auto upgrade my site has this issue not accessible at all that I had to manually remove the W3 Total Cache plugin folder then reinstall. What could be the issue? I have no other cache plugin. Opcache, page, object caches and minify were enabled.

    Hello @nazar78

    Thank you for reaching out.
    This issue is not specifically related to W3 Total Cache but to your hosting environment. As Stack trace suggests the problem is with the FastCGI response sizes so you should reach out to your hosting provider and check this.
    I hope this helps!

    Hi @vmarko,

    Thanks for responding. I have full control over my site (local NAS 16GB ram 50% usage). I currently have this off for a long time as I’m aiming for no buffering response, wasn’t an issue until now.

    fastcgi_buffering off;

    My site has low traffic but I can afford to turn on and increase the fastcgi buffers further than default. I’ll try and monitor. Thanks again for pointing out.
