Every time I hit “Update” inside Elementor the page stalls and eventually throws “Server Error 4040 not found.” Nothing else on the site is acting up and I haven’t touched themes, plugins, or core files recently. I already ran the usual first-aid—cleared the cache and briefly disabled a few plugins—but the error persists. I need someone who can jump in, trace the root cause (whether it’s a silent plugin conflict, a server rule, or a database hiccup), and leave me with an Elementor setup that saves normally again. Deliverable: I can edit any page in Elementor and click Update without seeing the 4040 error or losing changes. If you can pinpoint the issue quickly and walk me through any preventive steps for the future, let’s get started.
