Recency HTS Client card Data Export not Generating

Some facilities I have upgraded from 3.3.7 to 3.4.1 are failing to generate the Recency HTS Client card Data Export

What could be the problem.

Kindly share the error you’re getting.

It’s just says contact system administrator and the save icon becomes inactive. And when you check whether it saved, you find when it’s not saved

Kindly share your server logs or backup to emrtalk@musph.ac.ug
