Is there no log message above the error you sent? Did you restart weewx? In what directory did you change rtgd.py? John,
Let me clarify. I did exactly what Glen said and replaced the double quotes in the line. I then restarted weewx and got a similar error message. It looked to me as though it was pointing to the single quotes, which I replaced. I then restarted weewx and got the error in the previous message.
Next, I tried just retyping the line entirely and get the following error along with the output from the log.info. It seems to point to the line following the log.info line,which I did not touch!

Hey can’t be single quotes because there are single quotes inside the string. Replace the things that look like double quotes with actual double quotes. Glen, John,
I deleted and replaced the double and single quotes in the code. It turns out that single quotes threw the same error when I restarted weewx. Here the log output from the restart:

Thanks for staying with me on this!

John,
I deleted the max_cache_age line and retyped it, in case there was any text I couldn't see.
Here is the line you requested: File "/etc/weewx/bin/user/rtgd.py", line 2893
log.info(\u201cts: %s (%s), self.cache[obs][\u2018ts\u2019]: %s (%s), max_age: %s (%s)\u201d % (ts, ts, self.cache[obs][\u2018ts\u2019], self.cache[obs][\u2018ts\u2019], max_age, max_age))
^
SyntaxError: invalid character '\u201c' (U+201C)
That syntax error is the result of non-ascii characters in your log.info string. Specifically - smart quotes. They are showing up as \u201c and \201d instead.
Where you see " or ” ie :- 'double quotes' delete them and replace them with the plain " character from your keyboard. Use a plain text editor to do it and it will have no choice but to insert the correct character. Use nano, vim or whatever is your favourite editor
There is a subtle difference in their appearance and while they appear the same, they are most definitely not.
