Oh okay. I will uninstall all but system and protector to which module causing the issue. I will follow up

I am getting this error when I changed the php version on my Xoops 2.5.9 website to PHP 7.0. It works if left on PHP 5.6 but trying to change that to 7.0, 7.1, or 7.2 which are readily available on my dedicated server.

A problem has occurred on our server!

Please come back soon ...

Error : Error: Call to undefined function split())

So I reverted back to PHP 5.6 for now until I figure out how to get it to work on PHP 7

I tried to do it on a fresh install while PHP 7.0 is enabled and still get the error.
