Deactivating plugin breaks my site

Hi,

I have been using Autoptimize for a while now. I have some small trouble with my page. While troubleshooting I deactivated the plugin and that broke my site totally. Everything is now ok after activating the plugin again. I’ve been trying to figure it out why that happens every time I deactivate it. I’ve cleared all the caches that I can but nothing helps. So am I forced to use Autoptimize for now on or can I fix this problem easily somehow? I like the plugin though, just want to understand the case.

Thanks guys,

mikko
