Icons Not Working

I’m having the same problem.

Weather Underground has changed the link locations of all of their icons.

I updated the code for my client, should anyone want to use it, you are welcome to. However i am sure they will update the plugin themselves soon.

You can also edit the file and do a find and replace all for “icons-ecast.wxug.com/” and replace with “icons-ak.wxug.com/”

this is the wunderground.php

	<p>Use the following tags to modify how low and high temps display: <code>%%high%%</code> and <code>%%low%%</code>.</p>
	<ul>
		<li><strong>HTML is fully supported. This allows you to color-code:</strong><br /><code><span style=&quot;color:red;&quot;>%%high%%</span>/<span style=&quot;color:blue;&quot;>%%low%%</span></code> <em>outputs as:&nbsp;</em> <span style="color:red;">85</span>/<span style="color:blue;">55</span></li>
		<li><strong>Choose to only show high or low:</strong><br /><code>High of %%high%%.</code> <em>outputs as:&nbsp;</em> High of 85.</li>
		<li><strong>Use CSS classes too:</strong><br /><code><div class=&quot;temp&quot;>High of <span class=&quot;temphigh&quot;>%%high%%</span><br />Low of <span class=&quot;templow&quot;>%%low%%</span></div></code> <em>outputs as:&nbsp;</em> <div class="temp">High of <span class="temphigh">85</span><br />Low of <span class="templow">55</span></div></li>
	</ul>
	<hr style="padding-top:1em; outline:none; border:none; border-bottom:1px solid #ccc;"/>

	<h4>Using the <code>[forecast]</code> Shortcode</h4>

	<p>If you're a maniac for shortcodes, and you want all control all the time, this is a good way to use it.</p>

	<p><code>[forecast location="Tokyo, Japan" caption="Weather for Tokyo" measurement='F' todaylabel="Today" datelabel="date('m/d/Y')" highlow='%%high%%&deg;/%%low%%&deg;' numdays="3" iconset="Cartoon" class="css_table_class" cache="true" width="100%"]</code></p>

	<p><strong>The shortcode supports the following settings:</strong></p>
	<ul>
		<li><code>location="Tokyo, Japan"</code> - Use any city/state combo or US/Canada ZIP code
		</li><li><code>caption="Weather for Tokyo"</code> - Add a caption to your table (it's like a title)
		</li><li><code>measurement='F'</code> - Choose Fahrenheit or Celsius by using "F" or "C"
		</li><li><code>datelabel="date('m/d/Y')"</code> - Format the way the days display ("9/30/2012" in this example)
		</li><li><code>todaylabel="Today"</code> - Format how today's date appears ("Today" in this example)
		</li><li><code>highlow='%%high%%&deg;/%%low%%&deg;'</code> - Format how the highs & low temps display ("85&deg;/35&deg;" in this example)
		</li><li><code>numdays=3</code> - Change the number of days displayed in the forecast. Up to 6 day forecast.
		</li><li><code>iconset="Cartoon"</code> - Choose your iconset from one of 10 great options
		</li><li><code>cache="true"</code> - Whether to cache forecast results. Use <code>0</code> to disable (not recommended).
		</li><li><code>width="100%"</code> - Change the width of the forecast table
	</ul>

Updated the plugin and it still does not work 🙁

Hey Zack, where is the short code located. how long does it usually cache it for? Thx, great plug in

I am having the same problem – upgraded to new Version 1.2.5.1 and the latest WordPress after not updating for awhile, and now the WUnderground icons don’t work. I took the Widget offline and will wait a day to see if it starts working. If it doesn’t, I’ll come back here and look for help. I love this plugin!

Your tips worked. I am up and running already, about 6 hours after I started having the problems.

thanks a bundle. Working fine now again.
