Fatal error: Cannot redeclare class Services_JSON
December 09, 2008, 11:01:27 am
I tried to import contacts and get this error:

Fatal error: Cannot redeclare class Services_JSON in administrator/components/com_civicrm/civicrm/packages/Services/JSON.php on line 116

I have a copy of CiviCRM on my local machine and wanted to import the contacts from the local machine to the live one.

It might be possible that "Services_JSON" is declared in some other component.

Is there a fix for this. I have several components installed. JomComments, Attachments and JCal Pro.

You'll have to help debug and figure out which component is also including it. We dont know the conflict and hence dont know what/where to fix

 ??? I'm not a programmer, I don't know how to debug the program. I'm a designer with basic programming skills, if you give me some guidance, I definitely assist in any way I can.

sorry, you'll need to lean on one of your programmer friends and/or hire someone from our professional service listing: http://civicrm.org/professional/

I'll probably list it on Joomlancer and see what the bids look like. They are pretty reasonable.

Yep I am getting exactly the same problem, however I can't see how this could be a conflict with another program as it is pretty specific.

Here is the work around if you have Azrul products installed on your site:

To temporarily unpublish Components:

From the back-end Joomla Control Panel

Click on Extensions/Components
Disable JomComment, Community, MyBlog

To unpublish Plugins :

Click on Extensions/Plugin Manager
Disable  Azrul Video Mambot  and Azrul.com System Mambot

I wish I could take credits for this fix. Give thanks to my good friend Chris Miller at the www.webtool.com.

Thanks, Henrik

Excellent,

This resolved my inability to import contacts as I was running into the same JSON errors.

Thanks Much!

I have had this error too. One of the sites I am developing has K2 handling the layout, so it isn't feasible to turn the conflicting component off.

So I searched for the string 'class Services_JSON' in the two components so I could see what differences they had and how they were implemented.

As far as I could see the code for the two Services_JSON classes were identical. The differences however were that the K2 version of the class Services_JSON was wrapped in;

Code: [Select]
if(!class_exists('Services_JSON')){
class Services_JSON
{...}
}
you can see this at line 127 of administrator/components/com_k2/lib/JSON.php

So I did the same in administrator/components/com_civicrm/civicrm/packages/Services/JSON.php by inserting
Code: [Select]
if(!class_exists('Services_JSON')){at line 115
and
Code: [Select]
}at line 779.
I also needed to insert
Code: [Select]
if(!class_exists('Services_JSON_Error')){at line 782 and
Code: [Select]
}at line 791 because I was getting a similar class-redeclaration error after when testing the first set of inserted code.

With this simple test of class-existence, I have managed to resolve this conflict. I hope something like this is in a future update of CiviCRM.

I've just submitted it as a bug an uploaded a corrected copy of JSON.php

I hope I have done all of the right bits - all it should take is for someone to put the file in the right place for the next version.

Cross your fingers.

So I am having this same problem because I have JomSocial. I saw this thread and downloaded the corrected JSON.php from here: http://issues.civicrm.org/jira/browse/CRM-5255, which says the issue has been resolved and tested.

I copied it up to my server but I am getting this:
Fatal error: Cannot redeclare class Services_JSON_Error in /home/viri50/public_html/rlcfl.org/administrator/components/com_civicrm/civicrm/packages/Services/JSON.php on line 783, which is basically where I started.

I don't know a thing about php, and don't know how to read/apply a diff file. Can anyone point me in the right direction here?

Encountered the same error.  After reading previous post re: K2, I uninstalled K2.  Problem gone.
