This message appears to inform you that you are using the legacy version of the InDesign plug-ins (from February 2026).
The use of legacy plug-ins is a valid temporary workaround to an issue that may have arisen since support for type-on-path was added in late February 2026.
But you should return to the use of the current version of the plug-ins, as soon as technical support has fixed the issue you have encountered.
