Update:<\/strong> WordPress released Jetpack 3.0.0, followed closely by 3.0.1 claiming that it works 100% with WordPress\u00c2\u00a03.9.1 “according to its author.” (Spoiler alert, it doesn’t.) There seems to be a problem now in the Publicize & Related Posts<\/strong>\u00c2\u00a0features of Jetpack, making them\u00c2\u00a0the features I have to toggle off when I want to write a new blog post – which is terrible since Publicize\u00c2\u00a0is the one you want turned on when you post. Continue…<\/p>\n

For the past couple weeks, I have been unable to insert media into my WordPress Posts, or even see the Media listed out in the Media Gallery.<\/p>\n

Today I decided to bust out the web developer console and take a look at any error messages that came up in Firefox. There was one…<\/p>\n

x| TypeError: a is undefined<\/pre>\n
Unfortunately it’s an error spit out by jQuery, which is totally useless in tracking back to the actual problem.<\/p>\n
\"WordpressI am using the 2014 Theme from WordPress, and a short list of 10 plugins:<\/p>\n
    \n
  • Akismet<\/li>\n
  • Bad Bahavior<\/li>\n
  • Google Authorship<\/li>\n
  • Jetpack by WordPress.com<\/li>\n
  • Limit Login Attempts<\/li>\n
  • LinkWithin<\/li>\n
  • Post Ideas+<\/li>\n
  • Simple Google Sitemap XML<\/li>\n<\/ul>\n
    I disabled every plugin I had, and suddenly I was able to view the Media Gallery. Then I started enabling them one-by-one, and it turned out Jetpack was the\u00c2\u00a0culprit<\/strong>.<\/p>\n
    I started disabling each individual Jetpack feature:<\/p>\n
      \n
    1. Click the Learn More button<\/strong><\/li>\n
    2. The “Configure” button becomes a Deactivate<\/strong> button<\/li>\n
    3. Click the Deactivate button<\/strong><\/li>\n<\/ol>\n
      \"JetpackI went through them 4 at a time, starting with the first row, and tested the Media Gallery again, and it started working. So I enabled them one-by-one and it turned out the Publicize and Jetpack Comments<\/strong> features were the issue, however while turning plugins back on, I discovered that, Simple Google Sitemap XML, Post Ideas+, and Limit Login Attempts plugins<\/strong>\u00c2\u00a0also cause the issue. So they have been removed\/deactivated too.<\/p>\n
      This really sucks, since I count on the publicize feature to send my stuff to thepizzy.net’s respective social media pages…and the comments feature made commenting really nice (though I haven’t had a comment on a page here in a long time). And the Limit Login attempts is a good security feature to have.<\/p>\n
      One thing to note: these Jetpack features and plugins just happened to be the issue for this one particular blog of mine. I have others\u00c2\u00a0 that use similar plugins and features, even these causing the issue, and the Media Gallery works just fine on them. If you’re having a similar issue, follow this methodology and disable everything that isn’t a vanilla install of WordPress until the problem stops. Then re-enable all the features you really want to include until the problem comes back.<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"
