A new known Salesforce bug is being reported in the last 2 days -- SF displays an Internal Server Error message erroneously after students install Max's Pitch Package at the beginning of Lab 1b, apparently in Safari only.
Please note this does NOT affect the installation. The package is installed and functioning properly. Students can ignore the message and carry on with the instructions.
We expect a fix coming from SF soon -- hopefully in a few days. In the meantime, please let your students working Lab 1b know that they should ignore the message and carry on and/or switch from Safari to Chrome. Thanks!
Sorry for the hassle!
