Hi,
We have an old site in Kentico 3.1 that keeps getting an "Invalid License Key" every 2 months or so (it keeps happening again and again) when they key is valid. To remove the message, I have to restart the site in the CMSSiteManager's Administration panel.
The problem is that we don't have any warning and it is the client who is contacting us to correct the problem, which we want to avoid.
Please see the image below for more idea on the error:
Is it a common problem with Kentico 3.1? Do we absolutely have to upgrade to fix this?
Thanks.
Nathalie
