Here is an error I found in 6.15 and fixed it

Don't know if this is happening to others or not, but after I upgraded to 6.15, anyone can click on chat and have access, Even if you uncheck this on you plugin admins, it doesn't work. I compared both codes and it seems 6.15 code is a bit different. Here is how you fix the problem if you have it..

If you have 6.15, In root directory, open chat.php

Find this line towards the top:

$logged['member'] = member_auth(0,false );

you need to delete the "false" from (0,false)

Don't know why but with the "false" vistors have access to chat....

Thank you for this. When I removed false, the page was just balnk so I changed it to true and now its all good. So here is what I did.

/chat.php at line 32

change

$logged['member'] = member_auth( 0, false );

to

$logged['member'] = member_auth( 0, true);
