wordpress 3.2 Edit Post visual editor not working json missing

von Joern am 7. Jul. 2011 | Keine Kommentare

My problem: upgrading to WordPress 3.2 worked flawless, the sites worked as before, admin is even nicer than before.

BUT: As soon I switched to the Edit Post window, any javascript didn’t work, no visual editor, no logout dropdown, no Screen Options dropdown.

I disabled all plugins, switched to twentyten and twenty eleven, ‚reset‘ plugins folder, no chance.

So I had a look at my sites error log and found:

PHP Fatal error: Call to undefined function json_encode() in /srv/www/vhosts/mysite.com/httpdocs/wp-admin/includes/class-wp-list-table.php on line 905, referer: http://mysite.com/wp-admin/edit.php

Clearly to see: undefined function json_encode() called by wp-admin/edit.php

Checking my phpinfo() there was no json to see! So on my plesk 9.5.4 json is not enabled!?

The vServer is running on plesk 9.5.4 on a suse 10.3 with php 5.2.11-0.1

To enable this json stuff I found you need json.so and json.ini in folders mentioned below.

Looking on the servers root there is no json.so in \usr\lib\php5\extensions\ and there is no json.ini in \etc\php5\conf.d\

Lucky I found the correct rpm packet ‚php5-hash-5.2.11-0.1.i586.rpm‘ here:

http://autoinstall.plesk.com/PSA_10.0.1/update-rpm-SuSE-10.3-i386/

I downloaded this .rpm, opened up with 7-zip and copied the two included files to the folders they should be in. (using winscp)

After a Restart VPS in my Virtuozzo Panel I went back to my sites phpinfo to find a new entry:

json
json support enabled
json version 1.2.1

Now back to the dashboard of WordPress 3.2 checked if the visual editor in Edit Post is working now? YESSSS!
