What happened yesterday.
1. I'm logging in the forum, it says the theme is not right and then, when I tried to repair it:
"Sorry, the copyright must be in the template.
Please notify this forum's administrator that this site is missing the copyright message for SMF so they can rectify the situation. Display of copyright is a legal requirement. For more information on this please visit the Simple Machines website.

What to do now?

I even can't access our Admin panel... Seem so broken...

And can't read any topic...

I deleted the last theme. With the default it's working well now.
There is some missing information. Probably the hosting problems...
I re-installed our favorite theme. And it's working well then. Solved!
2. Today the forum stopped; down...!

3. A few hours later it's working as usual, with the good old theme and the information is here, but not the last one.
Many apologies if you register and/or wrote something and now there is no. Please re-register and/or re-write again, dear people!
