Out of the blue my site started to throw error 500 this morning.
I’m using php8.2
Fatal error : Uncaught TypeError: Unsupported operand types: string + string in /home/weather/public_html/PWS_livedata.php:1437 Stack trace: #0 /home/weather/public_html/PWS_index2.php(30): include() #1 /home/weather/public_html/index.php(38): include(‘…’) #2 /home/weather/public_html/_test.php(17): include(‘…’) #3 {main} thrown in /home/weather/public_html/PWS_livedata.php on line 1437
Interesting…similar thing happened to me too… https://discourse2.weather-watch.com/t/weird-problem-with-php/73281
I upgraded to v8.3 and the problem went away but that might not be something that’s easy for you to do.
Your website https://yr.meisal.com/ is working OK
Current PHP version is : 8.1.27
Correct data uploaded https://yr.meisal.com/PWS_print_file.php
Your website https://weather.meisal.com/ is getting a PHP 500 error
Your current PHP version is : 8.1.27 not 8.2
The error is caused by invalid data in the uploaded file.
Is that a realtime.txt file ?
Change line 1437 in PWS_livedata.php from
else { $new = $cu[2] + $cu[25]; ####### 2020-10-01
to
else { $new = (float) $cu[2] + (float) $cu[25]; ####### 2024-02-01
That way we can see if there are more problems with the data.
This is your data uploaded: https://weather.meisal.com/PWS_print_file.php
A lot of NULL values for your outside temp/hum
Also the time is not updated and stalled at 19:07
A screenshot comparing the uploads for your two websites
Well, the errors are solved with adepting that line in PWS_livedata.php
The dashboard is loaded correctly
But with temperatures of 17.8 Celsius, which corresponds to 0 Fahrenheit.
→ The NULL values are translated to zero values.
→ The temp-unit in the upload file is set to F.
Succes with trouble-shooting,
Wim
Yes, code change solved Error 500.
Thank you a lot Wim!
Will the code change be implemented future updates, or should I make sure maintain this change in my own copy of PWS_livedata.php?
Next challenge, which I have to solve myself, is why my Davis stopped updating 
There will be “pdates”
You changed your scrip as the data uploaded is invalid.
That will not happen again in a few years. 
Regards,
Wim
