That sounds incredibly frustrating! Domain-level crashes usually point to a serious conflict in how scripts or database queries are being handled between the plugin and your server configuration. When a heavy plugin starts dragging down subdomains, it’s often a sign that the system is overwhelmed by unoptimized data processing. I’ve found that the best way to avoid these “crashes” in my own digital environments is to use lightweight, external tools for complex logic. For instance, instead of running heavy on-site scripts for calculations, I use a real-time CZN Save Data Calculator to handle my resource planning and data tracking off-site. It keeps my main systems clean and stable. I hope you find the specific conflict in your error logs soon!
