New Install 4.10.2 Service Unavailable On Admin Dispatch

Hi, i get SERVICE UNAVAILABLE page, same one used when updating store,
but on the admin dispatch:

...../office.php?dispatch=products.manage

It is new clean install of the cs-cart 4.10.2

Is there anywhere that i can look why is doing that?

I could see the product at first, but after I've added an option, I started to see SERVICE UNAVAILABLE error

Kind regards

Hello

Other controllers work correctly?

Best regards

Check page source code (Ctrl + U) to see error message

Thank you for you help guys.

(Ctrl + U) helped :)

However, apparently the Reward points addon was causing the problem for some reason...
After I've disabled it, I can access the dispatch=products.manage in the backend again...
