Dear customers,
Some customers told me that they receive the error (500 internal server error) when they install OS Property on Joomla 3.1.4. We have learned and found it is the bug of Joomla 3.1.4. To solve the installation issue (not only with OS Property), you can install the Legacy plugin into your Joomla site before installing OS Property. We attach the Legacy plugin here so you can download it. This issue will be solved at Joomla 3.1.5.
To read more about issue, please follow this link :

Thank you very much
Dev team
