The problem was that the loop related code had been removed from the template file by a mistake without me knowing. I had to add this back in: <?php if (have_posts()): while (have_posts()) : the_post(); ?> and <?php else: ?> <h2><?php _e( ‘Sorry, nothing to display.’, ‘html5blank’ ); ?></h2> <?php endif; ?>
That sounds like a theme problem, since you have all plugins disabled. The theme has some error, possibly some extra spaces at the top of a file. I’d change to one of the ‘Twenty’ themes and see if the problem stops. If so, contact your theme’s support area. If problem persists with one of the … Read more
Hard to tell, since you didn’t share your code. But the error message tells you why. But if you are trying to DEFINE previously defined constants (which is what those are, since they were defined in wp-config.php – look at that file in the indicated line number), then that would be the cause of your … Read more
So I reinstalled WordPress on both my live and local environments and downgraded to version 5.4.2 and everything seems to be working just fine, so far. I’ll update if anything breaks again.
So I finally figured out the issue. It was a combo of needing to update the NPM packages and replace a few of the packages. Also removing the inspector component did the trick.
You should remove an additional } on line 18. Try the following <?php if (!function_exists(‘understrap_scripts’)) { /** * Load theme’s JavaScript and CSS sources. */ function understrap_scripts() { // Get the theme data. $the_theme = wp_get_theme(); $theme_version = $the_theme->get(‘Version’); wp_enqueue_style(‘slider-slider-styles’, ‘https://cdnjs.cloudflare.com/ajax/libs/slick-carousel/1.8.1/slick-theme.min.css’); wp_enqueue_style(‘lity-style’, ‘https://cdnjs.cloudflare.com/ajax/libs/lity/2.4.1/lity.min.css’); $css_version = $theme_version . ‘.’ . filemtime(get_template_directory() . ‘/css/theme.min.css’); wp_enqueue_style(‘understrap-styles’, get_stylesheet_directory_uri() . … Read more
The solution to this will require server level changes, this isn’t something you can fix by changing PHP files. Your host needs to install the mysqli PHP extension
Unfortunately you can’t just copy code that plays a completely different role and replace users with posts and somehow expect this to do what you want it. The reason you get a fatal error is because you’re passing in too many arguments (3) to the filter, when there are only 2 supplied. Here’s the code … Read more
When you say you removed the WP Super Cache plugin: did you deactivate the plugin, or just delete the plugins/wp-super-cache directory? I suspect the latter, because it looks like your site is still trying to load WP Super Cache files. You probably need to update your wp-config.php file to remove the define( ‘WP_CACHE’, true ); … Read more
The second line in your screenshot, the first Red line, is showing a typo in a Javascript file called common.min.js. If you have a plugin that minifies your javascript (Typically a cache or optimisation plugin) on your site, try turning that off. Failing that, try swapping to the default theme, then if you’re still seeing … Read more
