    Hooray! WordPress 4.7 “Vaughan” is here! But OMGWTFBBQ!? WordPress 4.7 broke everything?

    Don’t Panic!

    Before you go any further, make sure you’ve updated your plugins and themes to the latest versions, clear your browser’s cache and cookies and re-log into your WordPress dashboard.

    Still having problems? Okay, read on!

    This thread contains the known issues with plugins and themes found in 4.7. Please read this WHOLE topic and come back and check again later, as it will be updated.

    Remember to be calm, be patient, and be respectful. Volunteers are out here to try and help you, but we need your help too. All of the normal forum rules still apply. Remember, you are just as important as everyone else.

    If your post doesn’t show up right away, please be patient. With the higher than normal post volume, more posts get flagged as spam by our auto-spam tool. We’re working hard to keep the queue clear, but making multiple posts slows us down, as we have to go back and check if you already posted. Post once.

    • Do use proper capitalization in post titles and body. Punctuate your sentence properly and humanely, it helps us read.
    • Do use descriptive subject lines. “All permalinks broken since 4.7” is much better than “Augh! Help ASAP! This version is terrible!”
    • Do describe the problem clearly. Explain what you’re seeing, include error messages and link to screenshots if needed. Linking to your site, if the problem is on the front-end, also helps.
    • Do be patient. We know it sucks to be down, but posting multiple times doesn’t get you help any faster.
    • Do make your own topic unless you are using the exact same version of WordPress on the same physical server hosted by the same hosts with the same plugins, theme and configurations as the original poster. You may find it weird, but it will be easier for us to help you specifically if you have your own topic.
    • Do mark your topic as resolved when it’s fixed so we know not to come looking there anymore.
    • Do remember you’re not alone.

    Also keep in mind that not liking the direction of WordPress’s design is a not a bug. If you don’t like a feature, please don’t make a series of posts complaining about it. Look and see if someone already did, and post there, or consider joining the process earlier on (like in Beta or even test via SVN). What you’re seeing today is the result of thousands of hours of work and testing, and unless something is outright broken, it’s highly unlikely to be changed.

    Again, before you post:

    Make sure you’ve read this entire thread and New Features in 4.7 Codex Article.

    Go to your own install’s about page – example.com/wp-admin/about.php – to see what’s new.

    And then make sure you’ve tried…

    • Flushing any caching plugins you might be running, as well as server and/or browser caches. Not just your browser, but any op cache or content network cache as well such as Cloudflare. That will solve many weird JavaScript issues.
    • Flushing Managed host caches. Managed WP hosting often has special caches. If your host has a “Purge Varnish” or “Flush Memcache” tool, try that. You can ask your provider to flush memcache and Varnish for you if necessary.
    • Troubleshooting with your browser. Your browser can help you identify JavaScript issues or conflicts and this article can assist you in doing that diagnosis. This could help identify Visual Editor issues as well.
    • Deactivating all plugins (yes, all) to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s). If you can’t get into your admin dashboard, try resetting the plugins folder by SFTP/FTP or PhpMyAdmin (read “How to deactivate all plugins when you can’t log in to wp-admin” if you need help). Sometimes, an apparently inactive plugin can still cause problems. Also remember to deactivate any plugins in the mu-plugins folder. The easiest way is to rename that folder to mu-plugins-old
    • Switching to the Twenty Sixteen theme to rule out any theme-specific problems. If you can’t log in to change themes, you can remove the theme folders via SFTP/FTP so the only one is twentysixteen. That will force your site to use it.
    • Manually upgrading. When all else fails, download a fresh copy of the latest.zip file of 4.7 (top right on this page) to your computer, and use that to copy up. You may need to delete the wp-admin and wp-includes folders on your server (NOTE: do not delete the wp-content directory or your wp-config.php file) Read the Manual Update directions first.

    Core Changes

    Not a Bug

    I can’t add a video header to my theme: While WordPress 4.7 does introduce video headers, the theme you’re using must be built to support video headers. Contact your theme’s developer for details.

    I can’t see the other Customizer features detailed in the release post: As with the video headers, the theme you’re using must be built to support these. Contact your theme’s developer for details.

    I don’t see PDF previews: Although PDF previews are now a possibility, any already uploaded PDFs will not display thumbnails, and your server will have to be configured to support them (This means you need Imagik, ImageMagick and Ghostscript for thumbnails to be generated for you).

    Alternative texts are no longer created automatically for my images: The alternative text auto-generated by WordPress was not good for accessibility, this is why we changed this to instead have a blank value (defining it as merely a visual element and not an important part) by default. This means we leave it to the poster to define the appropriate text for assistive technologies to use.

    The language of wp-admin changed: With 4.7, we’ve introduced the ability to change your personal languages preference for the admin areas. You may have saved your profile with a new language chosen, or the default language was not what you expected it to be.

    Feature buttons are missing from the editor: To encourage proper use of HTML elements, and to reduce the misuse of confusing elements (such as underlines for example), the toolbars have been rearranged (and some options removed, although their keyboard shortcuts will continue to work as expected), and may be found by extending the toolbar at the top to show both lines of options.

    Additional CSS isn’t working: If you are running Jetpack, make sure you’ve updated it as it previously provided a feature like this, which should not seamlessly move over to the WordPress version.

    My virus scanning tool thinks WP 4.7 is a virus: Their library definitions aren’t updated yet. If you downloaded from WordPress.org, you’re fine. The same goes for any security plugins. Upgrade them and check again.

    I don’t have the new default theme, Twenty Seventeen: Unfortunately it seems the new default theme was not included in the update package for existing users, but you can grab a copy your self by going to Appearance > Themes > Add new

    Plugin and theme issues

    • W3 Total cache – Version 0.9.5.1 is incompatible with WordPress 4.7 and you may need to remove it to access your site (Removing the plugin directory is not enough, you also need to remove the db.php, advanced-cache.php and object-cache.php files manually from the wp-content/ directory).
    • Genesis theme sidebar issues – If you have a problem with sidebars in the Genesis theme then please upgrade to the latest version of that commercial theme.
    • Twenty Seventeen Icons are Huge – Older versions of Font Awesome will conflict with icon styles in the Twenty Seventeen theme, making Twenty Seventeen’s icons larger than expected. Please make sure that you’re using either the latest version of Font Awesome or the latest version of any plugin that’s bundling it.
