Hi,
I am running into a really odd problem. I have a wordpress install running on ubuntu 16.04 set up with xampp 7. The website is working fine, I have looked over the files permissions and everything is great even the .htaccess file is working well and the wordpress pages are being loaded correctly with mod rewrite. The problem only occurs when I try to save a post from the back end. If I am connected to the website via a remote computer it just throws a 404 error (with nothing in the logs) and when I am working directly on the server that has xampp installed on it and open the site admin via firefox and save a post it works perfectly fine.
It's really odd, I've searched for hours and have not come up with any solid answer.
Thanks in advance.
