What is the Safe Mode
RapidMiner Studio prompts the user whether to start in Safe Mode if the last startup failed. Safe Mode disables all extensions in the hope that RapidMiner Studio can successfully start without them. If starting RapidMiner Studio fails without Safe Mode, backup all extensions (see
“Where are plugins for RapidMiner Studio stored?”
for the two possible locations of extensions) and move them to a backup folder. Then re-add them one by one and start RapidMiner Studio each time to see when it fails to identify the broken extension.
