I did a search and didn't see anything for this topic, but I apologize if it's been done already. >_<;

I keep trying to assign a rider to my school Master. It says the rider has been assigned, but when I check there is no rider (I've refreshed the page and everything) and it also gives me this error message:
<b style="font-family: "Times New Roman"; font-size: medium;">Warning<span style="font-family: "Times New Roman"; font-size: medium; background-color: rgb(35, 59, 1);">: mysqli_close(): Couldn't fetch mysqli in <b style="font-family: "Times New Roman"; font-size: medium;">/home/horseede/includes/util/opendb.php<span style="font-family: "Times New Roman"; font-size: medium; background-color: rgb(35, 59, 1);"> on line <span style="font-family: "Times New Roman"; font-size: medium;">53

Here is a description of what I am doing.

I go to the horses profile
I click manage your horse
Click Assign Rider
hit the check mark to Hire a level 10 Rider
Gets a normal screen telling me a rider has been assigned... during this an
Error message pops up on the top left of the screen.
Exits the page to go back to the barn where the school master is.
School Master still doesn't have a rider.

I hope this is detailed enough for the admins and mods!
Hope you guys can help :)

You can't assign riders to them.

I already answered this question of yours in the help me section a few minutes ago too. Not sure why you posted here?
