I was making myself, after some advice ;), a Page Template.
This works well, but when I connect to a external DB, so not the wordpress DB I get a strange error:
WordPress database error: [Table 'my_db_name.wp_1_terms' doesn't exist]
So my DB where I want to connect to is placed in front of the normal wordpress, and I don't know why.
I have changed my "global" mysql connect to a $variable and tried to use that in my query, same issue.
What can I do wrong here ?
