While I was putting together a blog post for my site earlier this week, I noticed that I was unable to switch between the Visual and HTML views while writing the post. Seeing as I use both when writing posts to my site, I was not only confused, but a bit worried that I had somehow damaged my WordPress install.
One of the first things I did was try to do the same work on a different computer. After doing some testing in multiple browsers on the computer I use for writing didn’t solve the problem or show any inconsistencies, I figured that this would be the next logical step. Trying the same methods on my laptop served no solution either, so I knew it was something related to my WordPress install.
I then examined my collection of installed plugins to look through the ones I had recently installed. In order to free up some resources, I decided to install a plugin called Use Google Libraries which allows for me to use the CDN that Google provides for their Google AJAX Libraries API, which is very beneficial to those who use javascript libraries like jQuery and MooTools for their site. After disabling the plugin, this resolved the issue.
For those of you that may not have this plugin installed, a plugin like it may also be responsible for why you can no longer toggle between the views. Also, Google Gears has been known to cause a similar issue with previous versions of WordPress (ver. 2.8).
Right now I currently have the plugin disabled and will be searching for alternatives. Any advice for an alternative would be greatly appreciated!
Happy coding!
