Great until PHP 8

I’m looking for the fix but not know PHP too much, is it ok to share the changes with gist or somewhere like it?

I don’t remember where all the changes were. Basically anywhere you have an array using blah{x}, just switch it to blah[x]. Or just run the plugin in a PHP 8 environment, you’ll see it pretty quick.

I’ve tried to find any array using {} in wp-content/plugins/collapse-archives/

None of them use incorrect {} which should be []

According to the error message, it says

2022/08/31 16:01:50 [error] 1088#1088: *266661 FastCGI sent in stderr: "PHP message: PHP Fatal error: Uncaught TypeError: call_user_func_array(): Argument #1 ($callback) must be a valid callback, class collapsArch does not have a method "enqueue_scripts" in /home/foo/www/blog/wp-includes/class-wp-hook.php:307

seems like it crashed because WordPress changed the way to call plugin? This plugin register in an incorrect way?

For the “enqueue_scripts” error, @usuari0’s solution in https://www.ads-software.com/support/topic/an-error-occurred-11/ worked for me.

After fixing that, I still had the issue where upgrading to PHP 8.x resulted in WordPress displaying as a completely blank page – not even any errors in the logs. Like @whusnoopy I couldn’t find any instances of arrays using blah{x} but while I was combing through all the files I did discover a typo in defaults.php where line 27 had ‘taxoncmy’. Correcting this to ‘taxonomy’ (as referred to in other files) resolved the issue and I was able to upgrade to PHP 8.1 successfully.

Thanks to @deborahfitchett , it works after fix the typo

There are two places need to fix

change line 42 on /wp-content/plugins/collapsing-archives/collapsArch.php from

if (!is_admin()) {
    wp_enqueue_script('jquery');
    add_action( 'wp_enqueue_scripts', array( 'collapsArch', 'enqueue_scripts' ) );
} else {

to

if (!is_admin()) {
    wp_enqueue_script('jquery');
    add_action( 'wp_head', array( 'collapsArch', 'get_head' ) );
} else {

and change line 27 on /wp-content/plugins/collapsing-archives/defaults.php from

'post_type' => 'post',
'taxoncmy' => 'category',
'postTitleLength' => '');

to

'post_type' => 'post',
'taxonomy' => 'category',
'postTitleLength' => '');
