Beginning around May 2025 the Wix Editor does not always load. The error message is “There seems to be a technical issue. Wait a bit and then reload the page”. There is no consistent pattern to this. I have used many different browsers (Chrome, Edge, Brave, Firefox, Opera, etc.). Sometimes it loads, sometimes it doesn’t. I have cleared cache and browser history but that does not fix the problem. I am running the latest version of Windows 11.
We had an issue a little earlier on today, which might be what you were experiencing.
It’s since been resolved, but the timeline can be found here - Wix Status - RESOLVED: Multiple issues across Wix services - in case it helps identify if what you experienced aligns with these times
