What does that solve? Does this make vbshout work in 5.6.5 or is that a solution to the smilies list issue posed by LuckyRiver?

this is a quick fix of error in 5.6.5

YES, I am using vbshout on two sites running 5.6.5 after commenting out line 441 and removing 462 as you suggested. Thanks!

I was able to get it running on 5.6.5 with the help of @heugabel suggestions

but when I try to send to a certain user (shout target) I get the error "Error: 200 parsererror"

any idea?

TIA.

From what I can see, these modifications will enable vbshout to work on vb 5.6.5 running something like PhP 7.4
If you try to run it with PhP 8 even with these modifications you'll get a new error,

unexpected_error,Unsupported operand types: string - int

and vbshouts will not load.

I have to do some further checking but on my test forum it seems like vb 5.6.6 made the username of the shoutbox user disappear from the shout. The shout remains but to the left of it the username is no longer there.

php 8 works with vB 5.6.6

Throw the attached php file to the full path above.

When I look at your demo https://vbyilmaz.com/vBShout

I see this

is that how it will be without identifying the username of the user who is making the shout? To the left of each "shout" is a generic face

no username.

Okay this is what I found out.

The Yilmaz new shoutbox.php will allow shoutbox to work with PhP 8.

Without this new file, you will get the
unexpected_error,Unsupported operand types: string - int

error when you try to run shoutbox on PhP8. So the new Yilmaz file SOLVES that error - that error will go away and Shoutbox will run okay now on vb 5.6.5 running PhP 8.

HOWEVER, there is a new issue that has to do with vb 5.6.6 When you run 5.6.6 , the shoutbox username disappears from the left side of the shoutbox,

and there is no way to tell who is making the shout.
