Discontinued for the time being .There's no information if and when they will be reinstalled.

Hi, sorry if this is totally the wrong forum, but I didn't find one for issues...but I cannot view Problem 8. The box that normally describes the problem statement is completely blank. I've tried reloading, logging out and back in, etc., to no avail. Seems to only be problem 8. Thoughts?

Thanks!

(see attached screenshot)

Wow! How did that happen? You should probably post this in the Errors/Warnings/Bugs topic on the News, Suggestions, and FAQs board.

This also breaks the "View the details of all problems on one page" option. It shows nothing beyond problem 7.

Indeed. Yet, when you viewing all solved problems on one page, they do not stop at 8, but instead it just shows a blank rectangle like on its problem page, then carries on as normal. Very peculiar.

I can't open problem8.
Fix it plz.. :0

The issue is being investigated. Thanks for reporting it.

Yes, thank you for the feedback. It should be viewable again now.

[dsizzle]

Thanks for the quick response! It is working now.

I just read the "Proposed Release Schedule for New Problems" on projecteuler.net.

It's nice to have a double with problem 500 and 501 on the 31st January, celebrating the 500 limit!

But I guess the relase time of problem 506 is not correct: ("Problem 506: Sunday, 8th March 2015, 01:00 am")
Following the usual pattern, it should be Sunday, 8th March 2015, 05:00 am.

Thanks, fixed. However, following the usual scheme it is 2015_03_08_04 (server time).

A news item will be posted at the end of next week about the double release.

[wefrieke]

The date of the news item in which the double release is announced is a bit strange: "24 February 2015: Problem 500"

[hk]

Thanks, fixed.

Getting an error when trying to load the problem page: https://projecteuler.net/problems. Getting this:

A critical error was encountered loading problem data

And it goes to the "About" page.

Yes, thank you for letting me know. The problem should now be fixed and if it happens again it should fix itself automatically within 30 seconds.

There seems to be a problem with the LaTeX formatting in the private problem forums.
As far as I can tell, the problem occurs if you use two or more subscripts to the same expression, like this:
$$\sum_{i=1}_{i\le n}i$$
It used to work before, but now the formulas are not rendered.

Here are some examples:

I don't understand what effect you're trying to achieve? The website uses MathJax. On that page is a live demo and by testing your expression you will see it doesn't like it (make sure you wrap your function in dollar signs). If you're trying to place a subscript before the function being summed then place the function within curly braces.

For example, is this what you're trying to get...?
$$\sum_{i=1}{_{i\le n}i}$$

I used: \sum_{i=1}{_{i\le n}i}

[jaap]

The formula in asgerix's post is intended to be rendered as a summation with two lines underneath it, one with i=1, and below it a line with i<=n. That example is a little silly, but you do occasionally see sums with things like "p<N" and "p prime", one below the other rather than side by side.

BTW, it is very odd. At work asgerix's post rendered fine for me, but now at home its formula does not render at all, even though I am using the same browser (Firefox 35.0.1). The only difference is that at work it's 64-bit, at home 32-bit.

[mpiotte]

It can also be rendered with: "\sum_{{i=1} \atop {i \le n}} i"
$\sum_{{i=1} \atop {i \le n}} i$

Is no one else seeing "[Math Processing Error]" in red text in 3 of the last 4 posts? I'm using Internet Explorer if it matters.
