I have already reported this bug as a message to the admins But I was suggested to create this post as there may be more observations that can help Dr. J fixing what needs fixing. So not an encouragement to post "me too" messages. We are many on chat that has confirmed the following.
When you view the site without being logged in - most - but not all - song pages create a white empty page with the words Internal Server Error.
When you login you can view all songs.
Later we discovered that the https://www.ibandstand.com/topics/86 also creates Internal Server Error. Even when logged in. But that one seems to be happening to some and not to all. Happens to me.
If any other situations create Internal Server Error - it may help posting them below. Post exact URL and also which browser, and if you were logged in or not. That can be important to track the root cause of the bug.
Just learned one more thing for the https://www.ibandstand.com/topics/86 issue. The real URL is https://ibandstand.com/topics/86. Somehow the URL when in the chat room gets prepended the www prefix and that fails no matter who you are.
The issue with the songs is not caused by www prefix. I check carefully. There is no www. in front of the URLs when you try to view the page without being logged in.
So the /topics/86 thing is a red herring. Sort of. The www prefix works in most of the site but not with forum URLs
