Arrowchat v3.0 does not work on PHP 5.4

[Alexsandro]

The chat is successfully installed, but it is not possible to get into the admin panel and configure it because the empty() function is used in source code.
Error - PHP Fatal error: Can't use function return value in write context

Empty is available in PHP 5, but I think I may see what's going on here. Can you please open up a support ticket with your FTP info and admin access.

[Alexsandro]

No, I can't.
I replace

Code: Select all

if (!empty(get_var('token'))) 

to

Code: Select all

$tok = get_var('token');
	if (!empty($tok))

in admin php files, and I can login into admin panel now.
But when I try add a chatroom, or change any other settings, I got blank page with no errors in the php errorlog.

We won't be able to diagnose this without digging into the files and seeing what the problem is.

[Alexsandro]

I will try to update PHP to a newer version.
Which PHP version can you recommend for ArrowChat 3.0?

[Jason]

PHP 7+ is the best. Not just for ArrowChat, but for security reasons as well.

I was able to install PHP 5.4 on our server and experienced the issue. There are two problems which I have corrected in the v3.0.1 update.
