Hi there,

I have a linode 1GB VPS, Debian 7, Hiawatha 9.14, MariaDB and PHP-FPM. It seems to be a very fast, simple and stable combination so I'm very grateful for all the hard work.

However, I have a couple of small problems with my 2 Wordpress installs. The one I'd like to get fixed first though is that both installs suffer from a "The connection was reset" error immediately after clicking the upload button in either plugins, or themes.

This does not seem to be a uplaod size issue as fpm is set to allow 20MB uploads and uploading a theme of 10M still causes the problem.

Also (might be related) when I try to install a plugin, theme or update, the browser does not update with the progress. there seems to be a definite time constraint on the process as my browser tab icon spins for around 5 seconds and then stops.

I hope the below is enough info.

My php5-fpm php.ini is here http://pastebin.com/hLXTa2LX

Here is my hiawatha.conf

If you need anything further then please let me know


Thanks for looking!

Sorry, the title is wrong. I was going to post about wp super cache but decided to solve the above problem first.

When dealing with large uploads, there are two things to consider: does my webserver accept such a large request and does my CGI application accept such a large request? It seems you took care of the CGI application (PHP in this case) to make it accept, but not the webserver. You can make Hiawatha accept larger requests via the MaxRequestSize setting.

Thanks for the help Hugo. I'm now able to upload sizable files through wordpress. I've also solved another related issue.

Do you have a donation address?

Good to hear that it works. No, I don't have a donation address. That's not needed. Instead, you can help me make Hiawatha more known.

No Problem! I'll be plugging a blog which praises Hiawatha soon.

As a side note, I've done some tests with caching in Wordpress enabled and a 1.2 meg homepage on tools.pingdom.com loads in under 500ms with a perf of 99%. That can't be bad!!! (google fonts is the other 1%)

I'm very happy you are doing what you do!

Thank you
Nick

Thanks Hugo
