Since WordPress 4.3 dropped yesterday there have been a flood of problems that users are running into.
Many of the problems are due to plugins that did not get updated before 4.3 came out.
However, outdated plugins are not the only problems users are experiencing after updating to 4.3.
First, don’t panic. You can discover a lot of problems and solutions over at WordPress.org.
First you will want to read WordPress 4.3 Master List (NOTE: I had to be logged into WordPress.org for the Master List link to work) (I’d also read this first if you have NOT updated to WP 4.3). This Master List will give you some sound advice and steps to take; such as:
- Make sure you’ve updated your plugins and themes to the latest versions
- Clear your browser’s cache and cookie and re-log into your WordPress dashboard
If that does not help you then you should read through How-To and Troubleshooting and then and only then if you did NOT find your problem or solution then create a post of your own. And PLEASE read the instructions contained in the WordPress 4.3 Master List for how to post properly before posting.
The WordPress 4.3 Master List also contains some steps to take before posting your problem:
- If your host provider has a “Purge Varnish” option or if you can ask your provider to flush memcache on your server.
- 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 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
- Switching to the Twenty Fifteen 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
twentyfifteen. That will force your site to use it.
- Manually upgrading. When all else fails, download a fresh copy of the latest.zip file of 4.3 (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-contentdirectory or your
wp-config.phpfile) Read the Manual Update directions first.
Now if none of the above solved your problem then go forward and read through the How-To and Troubleshooting Forum and if you don’t see your problem, then please post and hopefully someone in the forum will be able to assist you.
I wish you all the luck in your updating and if you had a problem and found a solution I’d love it if you would take a second and share it with us by leaving a comment below or by sharing this article with others.
AND, if you HATE all this updating stuff, then please check out my Tranquility Plans and I’d be happy to do it for you.
