It looks like you’re defining distance() in a template file. As @wongjin pointed out in the comments, a template file may be included multiple times, and so on the second inclusion PHP will try to redefine distance(), resulting in a fatal error. Try moving the function distance(){ … } code to a separate file that … Read more
I’d suggest starting with classic themes, especially the Loop and the template hierarchy. That’ll give you a solid foundation of how WP has worked for most of its history. Once you’ve done that, you can bolt block themes on top of your existing sound base of knowledge the same way they were bolted on top … Read more
Nonces don’t store absolute time, but the number of ‘ticks’ since the start of the unix epoch, where each tick is half a day long by default. To check a nonce, WordPress generates the current and previous nonces and compares the result to the value you passed in. This means that the nonce lifetime needs … Read more
If you’re trying to get users with all roles (in your example, administrator and author), your code looks like it should work. If you want users with any role (administrator or author, you’ll need to split the string in the role attribute into an array using explode(), and use the role__in array. Something like this … Read more
Definitely not the right way to modify the main query on any given template. Hook to pre_get_posts instead and modify it there.

By default the comment reply link is generated by the get_comment_reply_link function and the comment form with the send-button by comment_form.

The issue was that for themes the .mo and .po files needs to be called {locale}.mo or .po not {textDomain}-{locale}.mo/po
If you have a persistent object cache setup, then transients will not write to the database: they’ll be stored in memory. Reviewing the definition of set_transient() this can be seen: if ( wp_using_ext_object_cache() || wp_installing() ) { $result = wp_cache_set( $transient, $value, ‘transient’, $expiration ); } Only if no external cache is in place do … Read more
There are two constants related to preventing editing of themes and plugins through the WordPress admin: DISALLOW_FILE_EDIT and DISALLOW_FILE_MODS. If these constants are set to true, editing themes and plugins in the WordPress admin will be disabled, and no core or plugin updates will be shown. Check if those constants are defined, and if they … Read more
As of WordPress 6.3, the in_footer parameter is now bundled into the args array parameter (source). The correct syntax for the wp_enqueue_script() function is now as follows (leaving out the named function parameter as it not officially supported by WP core): wp_enqueue_script( string $handle, string $src=””, string[] $deps = array(), string|bool|null $ver = false, array|bool … Read more
