XF 1.3 Single Thread error: "Premature end of script headers"


Well-known member
Hello guys,

I have a new community that everything that I do works fine. I have created a thread ( twice) and both times I get a 500 internal server error.

Contacting HostGator support the attendant told me that I'm with the following error:

"Premature end of script headers: index.php"

I have searched aroundfor this and people usually say that its a PHP version related issue.. But how would other threads ( i have only a few) I created before/after this aren't having any problem ?

Attempt disabling them, and then check again. If it stops happening, an add-on would be the cause.
