I get to the https://numbas.mathcentre.ac.uk/ login page and when I enter my details I get "502 Bad Gateway nginx/1.14.0 (Ubuntu)"

I've cleared cookies and tried on a different device.

TIA

Sorry about this. I made an upgrade to the editor yesterday, involving moving some things around in the database, and it turns out that the rearranged database query runs _very_ slowly. I didn't notice this on my development environment because it doesn't have much content! I've made a quick change to the query so it at least runs, and I'm going to look into optimising the original query now.

I've worked out what was making the queries slow, and rearranged things so they now run quickly. A satisfying outcome!

Please let me know if you see anything else in the next few days that I've accidentally broken.

Over the last couple of hours, I've been unable to create a new question.

Gives a Server error

Whoops - I split the database migration into two parts, so that I could quickly roll back if it went wrong, but that meant that a column which should eventually be removed was still present, so there was an error when creating a new question.

I've run the second half of the migration, and I can now create a new question.

yep, that was my debugging display while I fixed it. Should be OK now.

As a data point, I have just tried to create the new question and exam. It seems to work.

With best regards,

Timur Zaripov.
