 * Since the latest update of Link Library the website returns a 500 error. I have
   removed the plugin and Website works. Re add the plugin as a fresh download, 
   500 error returns.
 * Hosted on Windows IIS8 & 2012 Server with php7.0 and MySQL 5.6

 * I need more information. If you activate the WP_DEBUG option in the wp-config.
   php file, then instead of a sinple 500 error, you should see the actual PHP errors
   that are occuring.
 * With these errors, I should be able to identify the problem area and issue a 
   fix.

 * As mentioned, I only get errors when link-library is installed, fine without 
   and only since the last update.
 * Fatal error: Uncaught Error: Call to undefined function cmb2_get_option() in

 * I think that the problem is that you have another plugin installed that relies
   on the Link Manager being active. Since the new version of Link Library no longer
   on the legacy Link Manager, it no longer activates it.
 * Can you try installing the Link Manager plugin ([https://wordpress.org/plugins/link-manager/](https://wordpress.org/plugins/link-manager/))
   on your site, then updating Link Library to version 6.0?

 * Or look to deactivate the link monitoring function from your SEO plugin.

 * It was working perfectly up until Version 6 update the other day so something
   in the way that has changed is causing the problem.

 * Link Library 6.0 is a major re-work of the plugin, as I have been announcing 
   for 6 months through admin messages. So it does not surprise me that something
   is no longer working correctly. I will investigate more tonight.

 * From my side, no plugins have been added since this update and last plugin was
   added some months before hand.
 * Hope it can be sorted as the directory ranks very high on google and now is offline.

 * Did you try re-installing the older plugin version?
 * [https://downloads.wordpress.org/plugin/link-library.LinkLibrary_5.9.15.8.zip](https://downloads.wordpress.org/plugin/link-library.LinkLibrary_5.9.15.8.zip)
 * That should get you back up and running until I can investigate this further.

 * This will likely be resolved if you install the CMB2 plugin: [https://wordpress.org/plugins/cmb2/](https://wordpress.org/plugins/cmb2/)

 * I looked a bit more at your error messages. The error is actually coming out 
   of a plugin called Keywords to Links Converter. If you deactivate that plugin,
   the fatal error should go away.
 * Now, the error is that Keyworks to Links Converter uses the CMB2 framework. I
   am not sure why installing Link Library 6.0 breaks that link at the moment.
