Skin reverts to english after cheetagenerator runs [BUG]

[dystechnic]

Describe the bug
I use version 3.4.0 of the skin.
I use it with the nl translation and initially all is fine.The skin is in dutch as expected. But after a while the skin reverts back to en.

To Reproduce
Steps to reproduce the behavior:

1. enable dutch in weewx.conf (lang = nl) and in skin.conf (date_time_locale = nl-NL).
2. run wee_reports to generate the needed files.The skin is now in the correct language. (dutch)
3. wait for cheetagenerator to run. I check with 'systemctl status weewx.service'. This runs about every 5 minuts.
4. refresh the page in your browser
5. the skin has reverted to english in my case.

Expected behavior
The skin stays in the expected language. Dutch in my case.

Additional context
Version 3.3.0 didnot have this issue. Don't know if this helps or not.

As of this moment the skin is in english.

Can you please verify that the file skins/weewx-wdc/lang/nl.conf exists?

I forgot to include it in the "install script" (already fixed, see 091edd0), but I assume the file exists for you because you had copied it earlier.

However, I can reproduce this behaviour, but only on my local test machine, when I change the language on my production machine, it stays the correct one and does not change. So I assume its a config mistake somewhere, I will do some more research...

[Daveiano]

I think I figured it out, after looking in my weewx directory, I saw a lot of weewx.conf.backup files:

After removing these with

sudo rm weewx.conf.2022*
sudo rm weewx.conf.2023*

and restarting weewx, the language does not change anymore. Can you please have a look if it's the same problem for you?

[dystechnic]

Yes, removing the old log files did the trick.
I don't understand why, but thank you for finding this solution.

I don't understand why, but thank you for finding this solution.

Me neither but this is not related to the skin. The language is handled by WeeWX itself. I tested this and it is the same for the default Seasons Skin. You could post to https://groups.google.com/g/weewx-user/ if it bothers you.
