I just installed this one single plug-in to my website today and after doing so, immediately, the page the plug-in was set to work on … broke, or was disabled. It was still visible in my raw page listing, but even when I copied and pasted the URL directly, I still got a 404 Page Not Found error.
I deleted the plug-in from the page but that didn’t help.
I had to go to the plug-in directory where I installed it, and I had to deactivate it.
The moment I did that – the page I put it on was immediately visible again.
I hope this helps the developer. This plug-in does exactly what I need for my website. I’m supremely bummed. I’m using the Virtus theme (themeforest) and it’s version 6.4.3. Elementor 3.19.2
Last update has broke it. Somehow the plugin start working as collapsing categories instead of collapsing archives.
The author has released several versions since PHP 8.0 release but just ignores existance of PHP 8.0 / 8.1 although that’s pretty easy to fix. I just did it by myself but now all the not working updates are always popping up. I don’t want to do the fix again and again.
It works great except if you try to upgrade to PHP 8. The author uses {} to access some data elements instead of the standard []. You can fix it pretty easily but it would also be wonderful if the plugin was updated to fix this minor thing. I’d happily contribute a PR if the author had the code publicly somewhere (Github/etc.).
When I activate this plugin, an error occurred below.
Warning: call_user_func_array() expects parameter 1 to be a valid callback, class ‘collapsArch’ does not have a method ‘enqueue_scripts’ in /home/customer/www/harupets.com/public_html/wp-includes/class-wp-hook.php on line 307
Now I disabled it.
I confirmed it in the environment below.
WordPress 5.9.2
Collapsing Archives 2.1.3
