WordPress 5.6 image upload error: not a valid JSON response

For larger image file uploads I’ve been getting this error recently:

Reducing the image file size and then retrying avoids the issue, but this adds additional steps.

Multiple posts online like this one suggest this is an error with the permalinks and resaving the current settings on that page in the Admin panel will fix the error, but this didn’t fix it for me.

Looking around in my server logs, I found this error in my /var/log/nginx/error.log:

2020/12/23 00:36:45 [error] 36#36: *311 client intended to send too large body: 4132609 bytes

This post suggests adding a client_max_body_size param in nginx.conf (or increasing the value already there). I added a larger value than the size in the error and this fixed the issue.

nginx and php-fpm configuration errors

Moving an nginx install from Ubuntu 14.04 to 18.04 and upgrading to more recent versions of nginx, php, php-fpm, I ran into this error in my nginx config:

2020/02/28 04:45:47 [crit] 11784#11784: *1 connect() to unix:/var/run/php7.2-fpm.sock failed (2: No such file or directory) while connecting to upstream, client: 192.168.x.x, server: , request: "GET /index.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php7.2-fpm.sock:", host: "10.x.x.x"

The “No such file or directory” error is talking about the nginx connection to the php7.2-fpm.sock, rather than the file the GET request is for.

On closer look at where the .sock file is located, this was a subtle error to find and fix, but the fix was simple as I was pointing to the wrong path.

In my nginx default config, I had this line (migrating from a config for an older nginx and pphp-fpm version, this is where it was before):

fastcgi_pass unix:/var/run/php7.2-fpm.sock;

… I was missing a /php/ dir in the path, so changing to the correct path was the fix:

fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;

2 years later: 2 years of running WordPress and MySQL on Docker in a VPS

It’s been 2 years since I migrated this site from a native install on a VPS to another VPS running Docker. I covered my migration in a number of posts, the first of which is here:

Moving my nginx+mysql WordPress VPS native install to Docker containers on a KVM VPS

The surprising thing (maybe? maybe not?) is that the site has been up and running for the past 2 years with no issues. I think I rebooted the VPS a couple of times for reasons I can’t remember, but other than that the site’s been up reliably for the past 2 years.

It’s also been 2 years since I last renewed my SSL certificate, so time to do a couple of updates. More to come later.

Replacing GoDaddy’s free Workplace Email with Email Forwarding

For a number of years since I’ve had my kevinhooke.com domain registered with GoDaddy, I’ve taken advantage of the free domain email that came with your registration. Apparently this service is now being discontinued, leaving you the option to pay for Office365 email through GoDaddy as their replacement, or taking your business elsewhere.

Included with you domain there’s also the option of ‘Email Forwarding’ :

Checking in GoDaddy support online here, it looks like at least for now you can replace your hosted email with email forwarding, so your incoming emails to your domain email addresses can be forwarded elsewhere (like GMail):
