Does your password protection seem to be broken on your WordPress site? If your WordPress site uses a page cache (like Litespeed Cache), and you have password-protected posts, disable the page cache on those posts. (The same is true for pages or any other post type.) The password submission workflow, when your audience member puts … Read more
Maybe I should have known this. But I didn’t, to my detriment. Empty arrays are falsey. Like so. The rule that an empty array is falsey bit me when doing this sort of thing. Many SQL queries can return an empty result set, that is, a result set with zero rows in it. That’s usually … Read more
Our choir director, Charles Brown Jr., has programmed Randall Thompson’s Alleluia for early November. I guess I need to learn to count. A performance. Here are some YouTube practice tracks. This track has a female singing the TENOR line, and sometimes she makes a couple of rhythmic mistakes. So…just remember to be in the same … Read more
The good people at Gravity Forms were kind enough to give me a developer license to their plugin, to allow me to analyze their indexes on request from a user of Index WP MySQL For Speed. These are the tables. All of them look like they have OK indexes, except wp_gf_entry_meta, which has a couple … Read more

What’s this problem? WordPress plugins run on a variety of sites running on a variety of server configurations, and a variety of other plugins. It’s common for unexpected configurations to cause trouble for plugin users. Then, users open support threads saying “something went wrong.” The plugin authors then need to ask for configuration information to … Read more
Somebody asked how to set up a WordPress / WooCommerce shop with the Flatsome theme. Understand that this is a web site operations project, not a development project, at least until you get it basically working. For now, ignore any advice to use Bricks, Elementor, Divi or some other site builder. You’ve chosen Flatsome. Get … Read more
I started using UNIX when I loaded the 7th edition nine-track tape onto a PDP-11 in a university lab. The shell — bin/sh or as we put it back then, sh(1) — had a history command that would regurgitate recent command lines. I got in the habit of typing history | grep whatever to find … Read more
You can, but you’re using it in a different way than you would on a full-custom site. Back in the days of Adobe Dreamweaver, people crafted their web sites from HTML using an HTML-aware text editor.
