Hi. i am using .98.

When click on start plugin, I am getting this exception and it tells execution failed.

I have created some of actions in view, buy and rate.. it shows in statistics page also. but i am not getting any recommendations when hit otherusersalsoviewed

Hi!

It looks like problem with the auto archiving system. Is this a new installation of easyrec or already a long time running? Out of the box the archiver only works on actions older than 3 years, so this is strange behaviour anyway. You can try to disable the Slope One plugin in the tenant settings to get rid of the error.

Anyway, the ARM plugin runs seem to work just fine so you should get recommendations regardless of the exception. So it seems that you just sent too few actions so far or they are distributed in a way that no recommendations can be calculated.

Greetings
Stephan
