Possible causes include:

1. Outdated browser or operating system
   Minimal requirement for BP Studio is Chrome ≥ 66, Edge ≥ 79, Firefox ≥ 78, Opera ≥ 53, Safari ≥ 11.1 (or 11.3 for iOS), or Samsung Internet ≥ 9.2.
   Other browsers (especially those that are Chromium-based) might also work, but are not officially supported and there's no guarantee that all functionality will operate.
   If you haven't done so, please upgrade your browser (note that upgrading Safari requires upgrading the system) or use the latest version of Chrome, which is the recommended browser.
   It is also known that earlier versions of Windows 7 may cause issues with SSL certificates. Please try updating Windows if the website is marked "insecure".
2. Temporary bug
   Please try clearing browser cache data and reloading the app to update BP Studio to the latest version, which might have fixed the bug, especially on Safari, in which a known bug in its caching mechanism could lead to you seeing this error.

In all cases, the error has been reported to the author, and he will try his best to fix the issue when applicable.
If none of the above solved the problem, please come back later in a few days and see if the error has been solved. The author apologize for the inconvenience.
