Ask How do I handle plugin or theme conflicts that break site functionality?

I noticed some issues on my membership site after installing a new plugin. Some pages stopped working, and certain features disappeared. I'm not sure if it's a plugin conflict or a problem with my theme. I don't know how to find the cause or fix it without breaking more things. I want to keep my site running smoothly without losing important functions.
