Error 500 – Upgrade Core 4.4 & WP-Property 2.1.4

I should add all other plugins for security, content editing, backup, etc. upgraded with out issue. The only plugin that breaks the site is WP-Property.

I was able to clear the issue by zipping the plugin folder up to backup..I then removed the plugin folder which allowed the site to operate again.

I then unzipped the plugin folder, activated the plugin and it now works at the latest version of 2.1.4.

So that probably indicates something was conflicting with the site during the plugin update process, but the plugin files actually updated.

Thought this was resolved…but I think there is a PHP version issue.

I was able to re-activate the plugin on my development VPS with no issue…so I backed up the entire working site from dev and moved to Production BlueHost Shared Hosting…BOOM! failed!

I deactivated/reactivated on shared hosting still fails with Error Code 500.

BlueHost Stack:
PHP Version 5.4.24
MySQL Version 5.5.42-37

Development VPS Stack:

PHP Version 5.4.45
MySQL Version 5.5.47-MariaDB

Keep in mind this site was working fine running on the BlueHost Shared running WP 4.2.5 Core and WP-Property 1.42.3.

Hello,

As I understand, you have fatal error on trying to install/activate WP-Property 2.x.x which causes 500 Error. To see the error you should enable debug mode. See doc here.

define('WP_DEBUG', true);

And, be sure, that the errors are being displayed.

define('WP_DEBUG_DISPLAY', false);

Please, let us know, which error occurs on WP-Property 2.x.x activation.

Regards.

Maxim,

Thank you for the fast response.

To reconfirm, the Bluehost Shared Hosting Environment:

Apache Version 2.2.31
PHP Version 5.4.24
MySQL Version 5.5.42-37.1-log

Here are the Debug Log entries:

Hello,

Please, look through the related topic here.

Also, please, ask your host provider about your PHP version. I think, you may be wrong about current one.

The error, you mentioned, must not occur on PHP 5.3 and higher.
