That does help. Most definitely!
I get a similar error message but it still generates the image,
regardless of curr_cond_icon setting
What is different is that mine is a Warning, yours is Fatal so it
likely comes down to how strict php is set - in it's ini file
PHP Notice: Undefined index: in
/tmp/var/www/html/weewx/wxgraphic/index.php on line 480
PHP Warning: imagecreatefrompng(): Filename cannot be empty in
/tmp/var/www/html/weewx/wxgraphic/index.php
on line 480
I've had a look at that problem spot before, line 480 - looks like
I'm running with a few extra lines?? - but i couldn't see anything
obvious, and as it was running okay so I left it for later. Mea culpa.
Looks like 'later' has now arrived!
Your wxgraphic_weewx.txt output appears similar. I don't have AM in my
timestamp as I'm running 24hr time. Looks like the script compensates
for it.
So Yes. It could well come down to my /etc/php/7.0/apache2/php.ini
settings masking it.
error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT
display_startup_errors = Off
log_errors = On
But that aside, now has become later. I need to investigate and fix it.
In the meantime I'll edit the repo and turn that off, with a note.
Thanks for the heads up.
