Have a look in /home/weewx/weewx.conf, in particular look for the WEEWX_ROOT
config item (should be around line 14). Does it exist, is it correct. Look
at the lines above and below. Your weewx.conf should look something like this
one <https://github.com/weewx/weewx/blob/master/weewx.conf#L14> (well at
least the first so many lines). If in doubt post your weewx.conf making
sure you take out any sensitive info, passwords, addresses etc.
