Green Check Marks Newsletter Mailer - After Server Move

[djdavedawson]

Just recently moved Zencart to a new vps on same parent server. Now the newsletter mailer is not showing the green check marks one at a time anymore. It seems to be waiting until the entire loop finishes before displaying them all at once. We've checked all the settings between new and old vps and they are the same.

Has anyone experienced this?

OK, so the issue was with the ob_flush() function, here is what I had to do to get this working again.

1. Disabled Apache GZip Compression (mod_deflate)
2. Disabled PHP-FPM
3. Set these settings in php.ini:
output_buffering = Off
zlib.output_compression = Off
implicit_flush = On

There was also a way to do it while leaving PHP-FPM enabled by adding the following to the vhost configuation:

<Proxy fcgi://yourdomain.com>
  ProxySet enablereuse=on flushpackets=on
</Proxy>

There was also another thread about this too:
