logs on UPS not working

[haden]

Hi
Using Version: 4.9700 on Synology and domoticz lite app

I have installed the NUT_UPS plugin https://www.domoticz.com/wiki/Plugins/NUT_UPS.html
and everythings seems to work in the web interface using PC or Android chrome browser.
But using the app i'm not able to view any logs from the UPS device. Nohing happens when i click any of the buttons (day, week etc)
Other devices log function works fine.
