Color member error, users can't register !

[Twix !]

Hi to everyone,

A few moments ago I received some erros and guests can't register to my forum anymore and even I can't register an account from the admin panel. I'm not really sure why this happened, I didn't do almost nothing for this to happen so if you can help me solving this issue I'll be very happy. I don't know how many people tried to register an account and didn't work. I just found about this problem but I think it's happening for a while.

I'll attach some prints so you can understand better, I really need to solve this quick

As you can see in the first print, that line is missing. Why? How did it got deleted? And with what shoud I fill it ? In the second print you'll notice the error.. please help me solve this.

If you need more information please tell me and I i'll do my best to tell you everything you need to know !

Are you actually using SMF 2.1?

your server/host updated mySQL and it now requires STRICT compliance.
The mod you have is not compliant.

So, go into the database and give the member_color column a default value (usually NULL)

Well, that was actually very simple. Thank you very much ! Problem solved I'll mark this topic as solved
