Using $this when not in object context

Get blank page with error Using $this when not in object context
using J3.6.4 with PHP7.1 and OS 3.03

Any ideas why this happened?

Double checked the issue is when using PHP 7.1

Hi Adam,
Where do you use $this in OS Property?
Thanks
Dam

Thats the error message I get when use PHP7.1.

Blank page only the text Using $this when not in object context on all sites.

Even on the backed under stetting i get error

Hi Adam,
Can you send me the screenshot of that error?
Thanks
Dam

Again,
there is only a blank page with the text: Using $this when not in object context on all sites.
I switched back to PHP 7.0 and all fine.So the issue come when I switch to PHP 7.1.xxx

In frontpage all pages blank where you using OS property. In the backed when you want to go to settings in OS property

any progress?

Hi,
Your question isn't clear, so we can't answer you. In this case, you can submit ticket and send
1. The email you entered when you purchased OS Property from us so we can verify the transaction
2. Your site url with super admin account so we can check your modification.

Really not clear?
There are no modification!! Do you have a server with use PHP 7.1.xx? So you will see the error.

I track down the email as we working for them as freelancer not the owner

In case anyone else experienced this problem, I tracked it down to the use of JSite::getMenu();
It may be entirely unrelated, but there was an issue raised with the Joomla core here which provided a clue .

By replacing the variable definition for $menus - the problem appears to have been resolved.
The two occurrences I had to change were in :

components/com_osproperty/helpers/helper.php
[lines 4205 & 4249]

So the lines now look like this:

I'm running OS Property 3.0.9 on PHP7.1 on Apache 2.4 (MySQL 5.7).
