Caridad,
I don't get it… why do you say that the posts appeared again after the WPML troubleshooting?
If you go to "Classes" I can see that the translations ARE NOT THERE for the post "TRE™ Tension and Trauma Releasing Exercises"
Are you talking about another post? which one disappeared then reappeared?
If the solution was just to use WPML troubleshooting to bring back the lost translations I think that we would've arrived to this conclusion after 3 weeks of troubleshooting with Harshad from the WPML support team…
Let me know.
