As I understand it the path sandbox/modx/weather/31.png is the orignal path in the weather.txt file. I did try to change path manually and then ftp to my server but the path is overwritten by the snippet file when I hit refresh, indicating that all permissions are set correctly at least.
The problem is that somewhere in the snippet is a wrong configuration somewhere that is writing an invalid path to the weather.txt file and the outputting it. The result is that all the statistical information is correct. It’s only the icon path that comes out incorrectly.
I did replace the icons with another icon set, which are stored in the same folder as requested in the snippet install instructions. I gave the icons the same filename and ending so that in theory there shouldn’t be any problems. I also tried it with the orginal icons (the one from weather.com) but I still got the same error.
I will copy paste all the snippet file as I have it on my server. If you see any mis-configuration, then please let me know. All help is greatly appreciated.
The path to $wxIcons is exactly as the orginal path:
$wxIcons = 'assets/snippets/WeatherX/graphics'; // Path to Weather Icons
the template below the snippet call is as follows:
[!weather?&zipcode=`DAXX0009`&units=`metric`&provider=`blah`&clock=`12`!]
<div>
<img src="[+wxIcon+]"><br />
<p>Temp: [+wxTemp+]</p>
</div>
I use the call {{weather}} to call for the snippet.
The WeatherX.inc.php that is located in the include folder (can be found in version 1.02) is as follows:
<?php
