I see the template code and it looks fine. I want to see what you added in the php page. Actually, more specifically, I want to see if you registered all the variables for use in your template, so I want to see the template render code.
I didn't register anything infact..I just imply the procedure explained in the below link.. https://vborg.vbsupport.ru/showthread.php?t=229194
it says there is no need to create a php file or a plugin..I create a template called "custom_online" and put the above php in it..then I check "/misc.php?do=page&template=online" page it shows the page but it does not show the current active users..
I'd appreciate if you explain how I'd register the variables or what I should do..if you have time and can check, I can also give you admin pass etc..
