Navigating to <Siteroot>/admin/ page leads to a system error popup

[tonyrzhang]

Describe the bug
So I just setup netlify-cms on my site and I saw that when I tried to navigate to /admin/ I get an error popup below.

After clicking Ok, the admin page loads like normal and I'm able to interact with my collections, but I was just wondering what was causing this, since it's pretty alarming to our other users that modify the CMS content.

Thanks!

Applicable Versions:

• Netlify CMS version: 1.7.0
• Git provider: Github
• OS: Mac OSX 10.13.2
• Browser version Chrome Version 67.0.3396.99

This error message was added in #550 to notify the user when caching cannot work due to the localStorage being full.

You could try clearing the localStorage/cookies for your site if you wanted to.

@erquhart @Benaiah I'm not sure why this is really necessary. Does it help to create a popup for users, or should we just handle silently?

Shouldn't be a pop up, not sure why that's the case.

@erquhart Great! It was part of the initial PR which you reviewed, so I figured you might have an idea 😉😃. We should be able to rework the netlify-cms-lib-util/src/localForage.js file to remove that alert. @tonyrzhang Feel free to create a PR if you're up for that.
