Thanks for the bug report.

I was able to reproduce the bug by generating a 500 internal server error in save.php and fixed the javascript code in 16bde56#diff-79039f951efdff70e6cf3d4ed97ca425ed0d872fe0d0fc7d84b62ef97522c43eL2497-R2505

For the 500 internal server error from php please check your php and apache error logs to see what is causing the error.

Some common causes are big page/html that will exceed apache LimitRequestBody or missing write permission for html pages.
