My site says this in the top

"Warning: Undefined array key "auto_increment" in /customers/a/1/6/made2you.dk/httpd.www/res/x5engine.php on line 6057 Warning: Undefined array key "auto_increment" in /customers/a/1/6/made2you.dk/httpd.www/res/x5engine.php on line 6057 Warning: Undefined array key "auto_increment" in /customers/a/1/6/made2you.dk/httpd.www/res/x5engine.php on line 6057 Warning: Undefined array key "auto_increment" in /customers/a/1/6/made2you.dk/httpd.www/res/x5engine.php on line 6057 Warning: Undefined array key "auto_increment" in /customers/a/1/6/made2you.dk/httpd.www/res/x5engine.php on line 6057 Warning: Undefined array key "auto_increment" in /customers/a/1/6/made2you.dk/httpd.www/res/x5engine.php on line 6057 Warning: Undefined array key "auto_increment" in /customers/a/1/6/made2you.dk/httpd.www/res/x5engine.php on line 6057"

This is the site https://made2you.dk/brudepigekjoler.php

Where can I make this fine again. 

1. In the Websitex5

2. Or with the hosting compagny

Look forward to some can help me, I have seen this before on another site I have. It is especially when I choose the function in the webshop where I use stock of goods. It otherwise works fine with the number of items there at your disposal

Looking forward to hearing from some wise heads who are smarter than myself
