If you bought a license from us and once you enter it in wpCJ it said it’s not valid, please answer the following questions and if all your answers are YES, send us a email:

• Are you sure the license you entered into wpCJ is the EXACTLY the one we sent you?
• The license you entered into wpCJ is the same one shown in your wpCJ’s “My Licenses” module?
• It sounds pretty obvious but… are you connected to the internet?
• You are not behind a proxy, right?

If you are on WordPress 2.8 or later,

• Is wpcj.com and cj.com allowed to make external HTTP requests?

If your answer is I DON’T KNOW you must make sure they are:

• Make sure you have wpCJ version 0.0.24 or later installed.
• Open your wp-config.php file and make sure the constant WP_HTTP_BLOCK_EXTERNAL is either undefined or set to false.
• If for any reason,  WP_HTTP_BLOCK_EXTERNAL is set to TRUE, make sure a constant named  WP_ACCESSABLE_HOSTS exists and it contains the domains wpcj.com and cj.com. If it does not exists, add it below the WP_LANG definition:
  • define(‘WP_ACCESSABLE_HOSTS’,'wpcj.com,cj.com’);

Your PHP installation was compiled without the Soap library.

You can upload a dummy PHP file to your domain with the following code:

<?php phpinfo(); ?>

… and be sure that your site meets all the requirements.

You might need to install it manually or ask your hosting provider to do so for you.

Be sure you have uploaded all files to /wp-content/plugins/wpcj (do not rename this directory folder)

Also, do not forget to upload the php files in BINARY mode.

If you are getting this error when you are trying to activate the plugin, then you must upload all the php files again. Do not replace the old files: Delete them and upload them from scratch.

Remember to upload them in BINARY mode. That’s the main reason of the problem.

wpCJ needs the Zend Engine with the Zend Optimizer freeware library, version 2.0.0+, installed in your server in order to run.

Please, refer to the following page for more information about it:

http://www.zend.com/en/support/knowledgebase.php?kbid=179&view_only=1

The Zend Optimizer can be downloaded from: http://www.zend.com/store/products/zend-optimizer.php

The following hosting providers have Zend Optimizer pre-installed:

• Hostgator
• Bluehost

The following hosting providers need manual installation of the library:

• 1and1 (*)
  • 1and1 has an unorthodox way to install and implement the use of Zend Optimizer.In order to make it work in 1and1, you will need to upload a copy of the proper ZendOptimizer.so file to your webroot folder (/USER/homepages/xx/xxxxxxxxxx/htdocs/ZendOptimizer.so) and create a php.ini file inside that folder. This file must be copied also to wp-admin folder. Very Important!, the php.ini must contain these lines:

    zend_optimizer.optimization_level=15
    zend_extension=/USER/homepages/xx/xxxxxxxxxx/htdocs/ZendOptimizer.so

The following hosting providers does not provide the library nor allow you to install it, so wpCJ does not work on them:

• None so far.
