WebGui show "Processing"

Hi at all,

i have installed OCS Inventory on my Ubuntu 16.04.3 LTS machine with mysql and apache2, latest patches at all.

Everything is working fine, first inventory of a windows client shows "1 machine inventored today" in WebGUI.

But: i don't see any data anywhere? Whichever link inbetween the GUI i click, i always get a "Processing..." shown, nothing else?!

How can i see the data which have been inventored?

Hint: the windows log-file in ProgramData is showing "Inventory successful" and no errors at all.

Thanks for any hints,

Joe
