I have written
vb plugins any double quotes in html output has to be double escaped that is a PHP law. There is no getting around that.
vb plugin sytem works the same way. In fact the very
vb plugin tutorials cover the very same point I do. Any html must be escaped or you are in error with PHP.
If I enter a plugin in
vb without escaping quotes I get the same error you get on your site trying to enter invalid code. works exactly the same way.
The tutorial is placed in our FAQ forum here for a reason. I am not going to bore people with a long discussion on php law but I do explain the basics there.
