Fatal Error in convert_smilies in formatting.php – Issue with Non-Countable Valu

Hello,

I am experiencing a fatal error on my WordPress website that seems to originate from the formatting.php file, specifically within the convert_smilies function on line 3480. The error occurs when a non-countable value (boolean) is passed to the count() function, causing the following error:

Fatal error: Uncaught TypeError: count(): Argument #1 ($value) must be of type Countable|array, bool given in /wp-includes/formatting.php:3480

Details of the Issue:

• The error occurs when filtering content via apply_filters('the_content', ...).
• It appears that some non-countable data is being passed to count() in convert_smilies.
• The full stack trace points to interactions with the convert_smilies function during the rendering of content on single post templates.

My Setup:

• WordPress Version: [Provide your WordPress version]
• PHP Version: [Provide your PHP version]
• Active Theme: Impreza
• Active Plugins: Includes us-core and other standard plugins

Steps I Have Taken:

1. Added debugging to identify the problematic value, which turned out to be a boolean instead of array.
2. Attempted to resolve the issue by wrapping the count() call in an is_countable() check, but this change is overwritten during updates.
3. Verified that the error originates in formatting.php and occurs due to content passed via filters.
   
   
   My Request:
4. Could you provide a solution to ensure that the convert_smilies function safely handles non-countable values? Alternatively, is there an update or patch planned to address this issue in WordPress core?
5. I would appreciate your guidance on resolving this issue or preventing it in the future without modifying WordPress core files. If more details are needed, I can provide additional logs or server configurations.
   
   Thank you for your support.
   
   Best regards,xcull
