On one of my hosting accounts where I have 2 WordPress sites, I noticed in the Dashboard on both sites that the Visual tab was not working in the editor, and I could not make new posts. I could see the tab, but it was grayed out and nothing happened when I clicked on it.
So I went about searching for possible solutions and trying various things. Since I didn’t check both sites at first, I suspected it was the free theme I had uploaded on the first site. Sometimes themes can do strange things! So unfortunately, I wasted a lot of time looking at other themes and trying them out, only to realize that did not solve the issue.
Then I tinkered around with the plugins I had installed. That wasn’t it. I dug around in my WordPress template files, but nothing jumped out at me as being faulty. So then I moved to doing a fresh install of WordPress. That still didn’t solve the problem!
Finally, I came across the right solution, and it was such an easy fix! Apparently, this issue with the Visual tab has been a common problem with the release of WordPress version 3.5. If you have this same issue, just give this a try:
1. Log onto your server and go to the root directory. Look for the wp-config.php file and open it up for editing.
2. Before you tinker with code in any file like this, be sure to carefully copy the code and paste it into a Notepad file, as a backup copy in case you mess something up!
3. Write the line of code define(‘CONCATENATE_SCRIPTS’, false); toward the bottom of the file, just above where it indicates to “stop editing,” which you will probably see between a set of /* …….. */ marks, which are programming comments. Don’t forget to include the little semi-colon! And save and close your file, and log back into your Dashboard. This is how the code looked in my file:
define('CONCATENATE_SCRIPTS', false);
/* That's all, stop editing! Happy blogging. */
