I think there is a little mistake in the a php script. https://www.romulation.org/news/read.php When you click 'Post' there stands Array then message... Could it be possible you just typed echo before an array or did you write that on purpose?
You're supposed to write a message and then click post. If you don't you get redirected to an old script that's not really used anymore, but yeah, I should fix that.
