I'm raising this as an issue against something but I don't know what that something is yet.
On the 28th January I started looking at improving the performance of oik-plugins.co.uk.
I wanted:
a) to further test my slog-bloat routine and
b) to measure the effect of WooCommerce on the server response times.

Prior to activating WooCommerce I had made a number of changes for PageSpeed Insights and other recommendations:

  1. Updated .htaccess to prevent access to xmlrpc.php
  2. Installed Wordfence and its firewall
  3. Installed and configured autoptimize
  4. Updated .htaccess with changes applied by hummingbird-performance
  5. Updated plugins
  6. Improved some image file sizes

I then installed ( / reinstalled? ) WooCommerce at 4.9.2 and attempted to create a product.
Things started to go very wrong.

  • The php error log showed some Fatal errors occurring at 22:15
  • At 22:32 I noticed that one request had taken 600 seconds to complete.
/oik_sc_param/bw_pages-orderby-parameter/feed/,,600.744132,7.3.26,1736,5781,1146,54,1320,67,41,25,60,0.028146505355835,,,,17450,13.66.139.84,600.742743,2021-01-28T22:52:55+00:00,Mozilla/5.0 (compatible; bingbot/2.0; +http://www.bing.com/bingbot.htm),GET
  • Then the system stopped responding and the trace log went blank.
  • And to cap it all, a short while later, I lost the internet connection
  • The system was still buggered in the morning.
  • The trace file showed only 4 transactions running at 3:00:30
  • I started a chat with hosting.
  • They reset .htaccess to the bare minimum
  • They also tried to swtich to PHP 7.4 - up until this time it was 7.3.26
  • Switch was done around 08:02. It was switched back at 08:50.
  • 11:22 - After some mucking about I switched back to PHP 7.4.14

The mucking about involved.

  • 11:15 - Updating oik-block
  • 11:16 - Updating oik-blocks
  • 11:29 - Installing and activating oik-loader
  • 11:47 - reactivated WooCommerce

Now the site's working OK. .htaccess doesn't yet have the Hummingbird changes.
