If you are receiving this error message in Blender 2.93 or later, this will indicate that there is a compatibility error between your installed FLIP Fluids addon version and installed Blender version. You will need to update your FLIP Fluids addon version to at least v1.0.9b or later. FLIP Fluids version 1.0.9b adds compatibility support for Blender 2.93. FLIP Fluids version 1.2.0 adds compatibility support for Blender 3.0.
If you are receiving this error message (or a similar error) when trying to use the Bake operator, this may indicate that multiple versions of the FLIP Fluids addon are installed on your version of Blender and that a new installation was not able to overwrite an older file due to the previous version being in use.
The first thing to try is to restart Blender and test if the error still persists. If you are still getting an error message, uninstall and reinstall the addon. Make sure to follow the installation guide of restarting Blender before and after installation (See Updating the Addon).
This error is caused by a conflict with the Blend4Web addon. You will need to disable the Blend4Web addon to use the FLIP Fluids addon. This error has been reported to the Blend4Web developers here.
This error can be caused by placing the FLIP Fluids addon files in the incorrect location, such as directly in the scripts/addons directory instead of in the correct scripts/addons/flip_fluids_addon subfolder. To fix this error, delete the file scripts/addons/types.py which is causing a conflict with Blender's script files.
This error means that the fluid engine is in use and Blender is unable to remove it. Simply restart Blender and try again.
