I was trying to watch videos today and I got this message:

Can you try clearing your history and cookies incase you're seeing a cached page.

Also, is this appearing on all videos for you or just a few? just one ?

Which page is this appearing on?

It's appearing on all videos, any video I click sends me to this Oops Server Error message. Is this an uncommon ocurrence?

Yes, this is an uncommon occurence.

I observed the same problem about an hour ago. Now, after having cleared my browser history and the chess.com cookies, the videos are working fine again.

Thanks for the quick fix

I've tried this in Firefox and chrome and i can't replicate what you're seeing.

When did you start seeing this ?  Have you tried clearing cookies ?

it happens to me with the videos too. I think there is something bad going on. 

Ok thanks, i'll investigate further and see if we can get this fixed for you

Sorry :(

thanks because I like watching those videos. 

This should be fixed now.  Can you please clear your browser cache incase you're seeing old pages, then try instructional videos again for me ?

i'll try too :)

in the last couple of days i've been getting this message lots of times!

Yes but i need to know if you're seeing it now and where :)

Clearing the history and cookies worked, who knows why =) Thanks a lot for the help Kohai

good
