    <p>If Chrome DevTools is reporting a 404 for a .map file (maybe <code>jquery-1.10.2.min.map</code>, <code>jquery.min.map</code> or <code>jquery-2.0.3.min.map</code>, but can happen with anything) first thing to know is this is only requested when using the DevTools. <strong>Your users will not be hitting this 404.</strong></p> <p>Now you can fix this or disable the sourcemap functionality. </p> <h2>Fix: get the files</h2> <p>Next, it's an easy fix. Head to <a href="http://jquery.com/download/">http://jquery.com/download/</a> and click the <strong>Download the map file</strong> link for your version, and you'll want the uncompressed file downloaded as well.</p> <p><img src="https://i.stack.imgur.com/lfwrB.png" alt="enter image description here"></p> <p>Having the map file in place allows you do debug your minified jQuery via the original sources, which will save a lot of time and frustration if you don't like dealing with variable names like <code>a</code> and <code>c</code>. </p> <p>More about sourcemaps here: <a href="http://www.html5rocks.com/en/tutorials/developertools/sourcemaps/">An Introduction to JavaScript Source Maps</a></p> <h2>Dodge: disable sourcemaps</h2> <p>Instead of getting the files, you can alternatively disable JavaScript source maps completely for now, in your settings. This is a fine choice if you never plan on debugging JavaScript on this page. Use the cog icon in the bottom right of the DevTools, to open settings, then: <img src="https://i.stack.imgur.com/Ezwue.png" alt="enter image description here"></p>

    1. COI'm voting for this (even though you answered your own question) because for the first time ever I noticed it today. It was driving me a bit crazy trying to figure it out, then I noticed the same 404 error on 2 sites I was working on and the 'enable source maps' option came to mind...that's what I get for watching your dev tools talks and turning everything on at once. I'll go over the docs you provided.

    2. COI have two things to add. **1)** Downloading a jQuery map file is not enough, you will also need an uncompressed source code (otherwise you'll see an empty jquery-*.js file while debugging). **2)** If you are loading jQuery from one of the CDNs then all three files (map, compressed and uncompressed source code) are in the same location and you can start debugging right away.

    3. COFirst time that happens to me, **same error and same solution, Thanks!**. I have to add that was when I updated to `Chrome v29` and I'm using the minimized version of `jQuery v1.9.1`.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
