Fail to download data and display data on report

Hi all,

I deploy kobotoolbox using this script. This server has been running smoothly for more than six months but two weeks ago I started experiencing unusual things. When I open submission in Data > report tab it doesn’t show summary or data, This happens for all the forms. Also In Maps, it does not display anything and when I tried to download the data it gives empty CSV, XLS with the only header.
I don’t know if this makes sense and am a beginner in codding
