Error due to power outage!!

[sali...@gmail.com]

hello,

I'm contacting you because I've searched everywhere. There was a power outage at my house, and when it came back on, the Raspberry Pi booted up, but when I tried to access the weather station, I got errors. I checked all the files affected by the error, but nothing seemed out of the ordinary. Searching online, I saw that other people had encountered this problem, perhaps due to the database! I have a backup of my database (performed every 15 days). Do you have any ideas?

 I've attached the logs. 

Have a good evening.

Patrick

It's me again. Perhaps an error occurred due to the sudden power outage and corrupted some files.

 If I replace them with the original files, is that a good idea?

You need to post more of the log. See the wiki article How to produce a useful log.

Based on the small excerpt that you included in your post, I'd say that it's your configuration file, weewx.conf, that's corrupted, not the database. Specifically, a character 55 bytes in.

But without a full log, it's hard to say.
