I have checked your topics for the problems I have having with the upgrade to K2.

Joomla Version 3.6.5 Dev 2016.

Last weekend I upgraded my site with K2 for use with the RAXO modules.

I carried out the following:-

1. Imported all existing Joomla content to K2
2. All contract could be seen on the K2 schedule page
3. When I clicked on a title it would not open and I received an error message "Error decoding JSON data Syntax error.
4. Found on your site a fix to change the
Step 1: Edit "(JOOMLA_PATH)/libraries/vendor/joomla/registry/src/Registry.php"
Step 2:
In line 366 replace:
$obj = $handler->stringToObject($data, $options);
to
$obj_count = json_decode($data);
if(count($obj_count) > 0) {
$obj = $handler->stringToObject($data, $options);
} else {
$obj = $obj_count;
}


5. This allowed me to have access to the content, however I could then not open up any of the extension modules for my site.

6. The system then became unstable and I had to restore it from a system backup.

I like you product and think K2 makes Joomla so much better. Can you please help.

Hello,

For the JSON decoding error you need to look at this thread www.joomlaworks.net/forum/k2-en/46914-0-error-decoding-json-data-syntax-error

owever I could then not open up any of the extension modules for my site.

Are you getting any error messages?
