From the “I wish I’d thought of doing that sooner” department: this is a draft of the WordPress 3.9 forum sticky that will be posted to the How-To and Troubleshooting sub-forum. As before, the topic will be closed to new posts but all moderators (and those who can) will be encouraged to update the posts as new issues are identified.
This post is almost 100% copied from Ipstenu’s 3.7 post (3.8 did not need a topic like this) with some small editing made. There’s a lot being updated in 3.9 and having a topic like this can help users who run into issues.
I know it’s a last minute notice but if everyone can give this a read, help identify broken verbiage and comment on anything that may be missing I’d appreciate it. Some of the links are broken and will be replaced or updated with the 3.9 versions before publishing in the forums. Also “3.9 is here” will get updated with the official name.
Hooray! 3.9 is here. But OMGWTFBBQ!? WordPress 3.9 broke everything?
Don’t Panic!
This thread contains the known issues with plugins and themes found in 3.9. 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 3.9” 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 does not a bug make. 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 A pre-release of software that is given out to a large group of users to trial under real conditions. Beta versions have gone through alpha testing in-house and are generally fairly close in look, feel and function to the final product; however, design changes often occur as part of the process. or even test via SVN Apache Subversion (often abbreviated SVN, after its command name svn) is a software versioning and revision control system. Software developers use Subversion to maintain current and historical versions of files such as source code, web pages, and documentation. Its goal is to be a mostly compatible successor to the widely used Concurrent Versions System (CVS). WordPress core and the wordpress.org released code are all centrally managed through SVN. https://subversion.apache.org/.). 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 the entire Master List post – and the New Features in 3.9 Codex Article – https://codex.wordpress.org/Version_3.9
Go to your own install’s about page – `http://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.
- 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 A plugin is a piece of software containing a group of functions that can be added to a WordPress website. They can extend functionality or add new features to your WordPress websites. WordPress plugins are written in the PHP programming language and integrate seamlessly with WordPress. These can be free in the WordPress.org Plugin Directory https://wordpress.org/plugins/ or can be cost-based plugin from a third-party(s). If you can’t get into your admin dashboard, try resetting the plugins folder by FTP FTP is an acronym for File Transfer Protocol which is a way of moving computer files from one computer to another via the Internet. You can use software, known as a FTP client, to upload files to a server for a WordPress website. https://codex.wordpress.org/FTP_Clients. 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 Fourteen theme to rule out any theme-specific problems. If you can’t log in to change themes, you can remove the theme folders via FTP so the only one is `twentyfourteen`. That will force your site to use it.
- Manually upgrading. When all else fails, download a fresh copy of the latest.zip file of 3.9 (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. Read the Manual Update directions first.
- Troubleshooting with your browser.
