This broke my website, unforunately [v. 6.4.3] – [Collapsing Archives] Review

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
