Errors during install

[KHysiek]

I just have installed Articles on fresh MODX 2.2.14 advanced based site. As usual installer shows lots of errors in log, however it installs succesfully (I think).
Anyway I think it still should be fixed, cause you can miss real errors and this can lead to real PITA later.
My log:
