This seems to happen when a null-value is returned from any listener hooked into the posts_results filter. According to the docs the $posts argument/return value can only be an (possible empty) array of WP_Post objects. Seems the plugin is passing a null value. I’m not using strong typing on the function parameters, because I’ve seen this when plugins return values with types that should not be allowed. But I guess the usage of count of course breaks when the value is not an array.

I could of course check for null values before using count. But that would be me fixing something that should not happen. The docs clearly state the type of the filter’s arguments/return value, and other plugins/code should not return a null value there. I would suggest talking to the devs.

If you want a quick fix for your site:

In my plugin inside includes/posts.php function filter_posts_query on line #49 change the following to the code beneath:

if ( count( $posts ) !== 1 ) {
  return $posts;
}

if ( empty($posts) || count( $posts ) !== 1 ) {
  return $posts;
}

For the other plugin:

The “Ajax Search Lite” plugin hooks into the same filter and returns the result of its custom ASL_Query object. This object’s $posts property is untyped and could therefore be anything. The developer(s) should add code to catch non-array values and return an empty array instead (imho).

Hope that helps!

I understand, thank you for the feedback! I looked into it and overlay UI is kind of complex and something I don’t want to implement in the custom block myself.

I will have a look into better supporting the cover block inside the slider. As a quick workaround, you can put a cover block inside a slide and apply the following CSS in your (child) theme/custom CSS in site editor:

.wp-block-good-slider .wp-block-good-slider__slide > .wp-block-cover {
    width: 100%;
    align-self: stretch;
}

This will make a cover block stretch the full width/height of your slide. I have not tested this extensively. But in a quick test it worked well enough.

I’ve also opened a GitHub issue here and here to track this. But I can’t promise any timeline atm. PRs are welcome though 🙂

I can confirm this in a quick test. The slide block does not support the align/alignWide block support because (if I remember correctly) it somehow messed with swiper styles.

But I tried to make the slide block work similar to the cover – it has most of the same block supports: background color, background image, spacing, dimensions, content position etc. Is there something you are missing?
