Your StdReport and DatabaseTypes sections use relative pathnames based on WEEWX_ROOT being expected.
https://www.weewx.com/docs/5.2/upgrade/?h=weewx_root#weewx_root-is-now-relative-to-the-configuration-file has a non-breaking change in that area. Guessing a 5.2 upgrade might solve your issue since WEEWX_ROOT is optional in 5.2 now. I left it in my .conf files anyway, FWIW.
