Unable to get Campaign list

I am using CMS 1.7.8, and in the last days I no longer had access to the campaigns menu, the message: Unable to get list of Campaigns

Is there anything relevant for it logged in CMS log page? (if not perhaps go through report fault wizard).

Were there any recent changes made? Can you look up the campaign table in database to see if it has records there?

It would be also good to upgrade your CMS to at least 1.7.9 .

I’ll do those tests.
Thank you so much, Peter
