I've seen this happen a lot when php spits out a warning or something and it breaks the json. In your php.ini file be sure that error and warning display is being suppressed.

I think this is the detail you were looking for. Now what do I do?

<br />
<b>Warning</b>:  Missing argument 2 for CRM_Core_Action::formLink(), called in /home/fog123/public_html/wp-content/plugins/civicrm/civicrm/CRM/Mailing/BAO/Mailing.php on line 2816 and defined in <b>/home/fog123/public_html/wp-content/plugins/civicrm/civicrm/CRM/Core/Action.php</b> on line <b>207</b><br />

I found a file called php.ini. This is all it says.

max_execution_time = 60;
memory_limit = 64M;
upload_max_filesize = 128M;
post_max_size = 128M;

Thanks,
I had already done that exact search and, while browsing the suggested responses, I realized that covering up warnings about missing and invalid arguments is NOT a solution. This is a bug. In some circumstances a temporary workaround to suppress a non-fatal bug by perhaps suppressing the warnings from only the php file that is generating them might be appropriate, but a global suppression of all warnings is pretty bad practice. In the long term such a habit leads to gradually deteriorating code quality. I think that instead I will submit a bug and live without the functionality until it is corrected properly.

good answer that puts a different spin on the idea. I'll try it. Thanks.

I have this error also and originally posted it here: http://forum.civicrm.org/index.php?topic=32493.new;topicseen#new.  I applied the patch located here: https://github.com/pratik-joshi/civicrm-core/compare/civicrm:4.4...CRM-14731 but it didn't fix it for me.  I still get the JSON error and the mailings aren't listed.
