Modal with content depending on opening hours
if you run your site under an url like example.com/dat/fresh/site/, remove the first slash in the href, like:

&lt;a class="colorbox-node" href="node/1?width=600&amp;amp;height=600"&gt;Test link&lt;/a&gt;


or change to full path, like:

&lt;a class="colorbox-node" href="/dat/fresh/site/node/1?width=600&amp;amp;height=600"&gt;Test link&lt;/a&gt;
