I have quite succesfully managed to set up my MD Visual theme, after a LOT of manual work (but that's another message another time). Now, I cannot manage to get the popular content views to work. (The other views work as expected.)
I have enabled the Statistics module in Core, and I have enabled "Enable access log" under Configuration >> Statistics >> Access log settings. The statistics reports seems to work fine.
My site has some test content for the appropriate content types, and not much else in terms of modules and other configuration. The preview for the "Popular content" views are always empty, it seems that some search fails. Further, on the "Popular today" page, I get the following error message:
'Exception: SQLSTATE: Integrity constraint violation: 1052 Column \'uid\' in field list is ambiguous'
Please point me in the proper direction. I have checked permissions and all seems to be OK there. I suspect that something goes wrong with the imported view code.
