Tech support has been working this issue which appeared after a shift in hosting platforms.

The review "gremlin" has no apparent pattern and strikes wherever and whenever at will.

Two workarounds:

-- post the review without the ROS; if successful, return to the review and edit in the ROS hidden portion

-- post the review in an entirely different forum than the one intended and staff can relocate the review accordingly.

Sorry, but that is the best we can offer at this moment.

Happy Hobbying!
