We successfully completed the upgrade to WordPress 4.0 early yesterday afternoon and from this end saw no problems. If you notice anything out of whack please let me know ASAP. However, there is one caveat as mentioned in yesterday’s e-mail to everyone:
There is a small chance that some themes will “reset” their sidebars. If any content disappears from your sidebars check the “Inactive Widgets” section of your Widgets page on the Dashboard. More often than not, missing content has been moved there. This shouldn’t happen but there is a small chance sidebar material will completely disappear and will need to be recreated. Unfortunately this is unpredictable at best so I can’t give anyone a more specific heads up than I’m doing here.
My next step is the training videos. Most of them are done, but not all. Today and tomorrow I’ll be uploading the ones that are complete to YouTube, posting each as their own blog post, and updating the list on the Online Training page. For any video that doesn’t yet have a new version, I’ll leave the old version up and mark it accordingly.
And, for those of you that prefer print materials to learn from or to have as a reference I’d like to point you to the WordPress 4.0 User Guide from interconnect/it. They have a free download version of their user manual and it is a great resource. (There are some minor differences based on the customizations we’ve made but you probably won’t notice them all that much.) Just head on over to their site, click the big Get it Now button, then select the free version. I’ll also be linking to this on the Online Training page for future reference.
