PHP 8.3 Cache breaks site when using API

The Code in the functions.php: (But i have deleted the urls and server path)

function worldstar_meta_comments() {
	global $post;
		if($post->post_type == 'post') {
			if(!empty(get_post_custom_values('ThreadID'))) {
				
				require_once "some/static/path/wcf/global.php";
				$threadid = get_post_custom_values('ThreadID')[0];
				$thread = new \wbb\data\thread\Thread($threadid);
				$comment = $thread->replies;
				$commentCount = strval($comment);
				$lastpost = $thread->lastPostID; 
			
			if ($commentCount == 0) {
				return '<a href=".../index.php?thread/'. $threadid . '&postID=' . $lastpost . '#post' . $lastpost . '" target="_blank"><span class="meta-comments">' . $commentCount . '</span></a>';
			} else {
				return '<a href=".../index.php?thread/'. $threadid . '&postID=' . $lastpost . '#post' . $lastpost . '" target="_blank"><span class="meta-comments site-commentcount">' . $commentCount . '</span></a>';
				}
			}
		}
}

(And i have also a comments.php, which includes the api form the forum, but i think its the same problem.)

Sadly, because of the error, i deactivated the api-functions in the live environment. We have a testing environment. But this is not a public site, is there a way I can send this to you personally?

Thank you very much!

Hello @vmarko ,

sorry, we are on a shared hosting, so its not possible to use Redis or Memcached. The Options and PHP Modules are not available. I can only switch to Disk Basic Mode.

thanks you

Hello @vmarko ,

we testet “Disk: Basic” Mode in a dev environment, but the now the error occurs here too 🙁

“Don’t cache” is selected there. The other available Option is only to disable WordPress REST API. But it makes no difference to switch it.

Hello @vmarko ,

i have send the bug report.

yes, but its really strange, if i purged the cache on my device for some browser its okay. But on other devices the site is still broken 🙁
