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.

New BBS documentary: Back to the BBS part 1

There is a new documentary about BBSes posted to YouTube this week, ‘Back to the BBS’. Rather than focusing on the history of the BBS such as Jason Scott’s awesome ‘BBS The Documentary’, this one looks at using BBSes in the current time, and why there is an increasing interest in using BBSes today.

Part 1 is 43 minutes and walks through using telnet based BBSes today, and includes a number of interviews with people looking back at when BBSes were in their height of popularity, and also interviews a number of Sysops of current day active BBSes and their users.
