k i Read me first / How to write a bug report
slester   3
N May 4, 2019 by LauraZed
Greetings, AoPS users!

If you're reading this post, that means you've come across some kind of bug, error, or misbehavior, which nobody likes! To help us developers solve the problem as quickly as possible, we need enough information to understand what happened. Following these guidelines will help us squash those bugs more effectively.

Before submitting a bug report, please confirm the issue exists in other browsers or other computers if you have access to them.

For a list of many common questions and issues, please see our user created FAQ, Community FAQ, or For the Win! FAQ.

What is a bug?
A bug is a misbehavior that is reproducible. If a refresh makes it go away 100% of the time, then it isn't a bug, but rather a glitch. That's when your browser has some strange file cached, or for some reason doesn't render the page like it should. Please don't report glitches, since we generally cannot fix them. A glitch that happens more than a few times, though, could be an intermittent bug.

If something is wrong in the wiki, you can change it! The AoPS Wiki is user-editable, and it may be defaced from time to time. You can revert these changes yourself, but if you notice a particular user defacing the wiki, please let an admin know.

The subject
The subject line should explain as clearly as possible what went wrong.

Bad: Forum doesn't work
Good: Switching between threads quickly shows blank page.

The report
Use this format to report bugs. Be as specific as possible. If you don't know the answer exactly, give us as much information as you know. Attaching a screenshot is helpful if you can take one.

Summary of the problem:
Page URL:
Steps to reproduce:
1.
2.
3.
...
Expected behavior:
Frequency:
Operating system(s):
Browser(s), including version:
Additional information:


If your computer or tablet is school issued, please indicate this under Additional information.

Example
Summary of the problem: When I click back and forth between two threads in the site support section, the content of the threads no longer show up. (See attached screenshot.)
Page URL: http://artofproblemsolving.com/community/c10_site_support
Steps to reproduce:
1. Go to the Site Support forum.
2. Click on any thread.
3. Click quickly on a different thread.
Expected behavior: To see the second thread.
Frequency: Every time
Operating system: Mac OS X
Browser: Chrome and Firefox
Additional information: Only happens in the Site Support forum. My tablet is school issued, but I have the problem at both school and home.

How to take a screenshot
Mac OS X: If you type ⌘+Shift+4, you'll get a "crosshairs" that lets you take a custom screenshot size. Just click and drag to select the area you want to take a picture of. If you type ⌘+Shift+4+space, you can take a screenshot of a specific window. All screenshots will show up on your desktop.

Windows: Hit the Windows logo key+PrtScn, and a screenshot of your entire screen. Alternatively, you can hit Alt+PrtScn to take a screenshot of the currently selected window. All screenshots are saved to the Pictures → Screenshots folder.

Advanced
If you're a bit more comfortable with how browsers work, you can also show us what happens in the JavaScript console.

In Chrome, type CTRL+Shift+J (Windows, Linux) or ⌘+Option+J (Mac).
In Firefox, type CTRL+Shift+K (Windows, Linux) or ⌘+Option+K (Mac).
In Internet Explorer, it's the F12 key.
In Safari, first enable the Develop menu: Preferences → Advanced, click "Show Develop menu in menu bar." Then either go to Develop → Show Error console or type Option+⌘+C.

It'll look something like this:

dcouchman   0
Jan 18, 2018
If you find content on the AoPS Community that makes you concerned for a user's health or safety, please alert AoPS Administrators using the report button (Z) or by emailing sheriff@aops.com . You should provide a description of the content and a link in your message. If it's an emergency, call 911 or whatever the local emergency services are in your country.

Please also use those steps to alert us if bullying behavior is being directed at you or another user. Content that is "unlawful, harmful, threatening, abusive, harassing, tortuous, defamatory, vulgar, obscene, libelous, invasive of another's privacy, hateful, or racially, ethnically or otherwise objectionable" (AoPS Terms of Service 5.d) or that otherwise bullies people is not tolerated on AoPS, and accounts that post such content may be terminated or suspended.

CurlyFalcon55   40
N Yesterday at 7:11 PM by cz1917
Summary of the problem:
Whenever I push the big, top right "Reply" button– NOT THE SMALL LITTLE "QUICK REPLY" BAR ON THE BOTTOM, and reply, I can't scroll down all the way to the bottom of the thread that I just posted in. Sometimes, very rarely though, I doesn't scroll down all the way when I push the "Quick Reply" bar.

-----Steps to reproduce:

1. Go to the link above.

2. Click any thread or create a new one.

3. Click the "Reply" button, not the quick reply bar.

4. Type a reply.

5. Push the "Submit" button.

6. Try to scroll down. if you’re lucky, the problem will reproduce.

-----Expected behavior:
To scroll all the way down.


-----Frequency:
Almost every time I push the big "Reply" button, sometimes (but rarely) when I push the "Quick Reply" bar.


-----Operating system(s):
macOS Sequoia 15.4.1


-----Browser(s), including version:
Chrome, (I don't know what version)


-----Additional information:
-It rarely does it in the "Quick Reply" bar.
-It almost always does it in the big "Reply" button on the top right.


-----Can anyone reproduce?

Redirect of old aops links to new links
Kempu33334   1
N Yesterday at 3:57 PM by AlexHome
Would it be possible to redirect users from a /Forum/[...] (which are the old aops urls) to the corresponding new link instead of to the 404 page?

It seems that it shouldn't be too difficult, as generally, all that has to be done is:

Old link: https://www.artofproblemsolving.com/Forum/viewtopic.php?f=[X]&t=[Y]&[Z]
New link: https://www.artofproblemsolving.com/community/h[Y].

For example,

https://www.artofproblemsolving.com/Forum/viewtopic.php?f=41&t=46819&hilit=Putnam+1990
https://www.artofproblemsolving.com/community/h46819

so the "Forum" is replaced with "community", the "t=" becomes "h" and the other things go away.

Environment: iOS 18.1.1, iPhone 14 Pro

When you type an answer in the iOS app, the number is not displayed in the text box. If you type the right number it will be submitted properly, it’s just not displayed.

The issue can also be reproduced on a 11” iPad Pro.

Thanks for looking into it.

Favicon Not Loading In Classroom

In my classroom (I am specifically taking 4210 Calculus) the favicon isn't loading. Developer tools says the server is throwing a 404 error. This obviously isn't a big deal but I thought I'd let someone know because I'd much rather have the happy AoPS cube than the generic world symbol. Thanks guys!

Hi,

Sorry, I am new to using forums, please let me know if this is allowed(if this should be in site support).

I have created a math contest, and was wondering if it would be fine to put in the Contests and Programs forum so more people would participate in it. Would this be allowed?

Thanks in advance!

Processing module python not working
Demetri   13
N Jul 23, 2025 by Demetri
The following code doesn't work, because canvas isn't implemented for the processing module:
import processing
def setup():
    processing.size(200, 200)
def draw():
    processing.ellipse(100, 100, 50, 50)
    processing.noLoop()
processing.run()

I believe this is an easy fix, someone just forgot to add the line "Sk.canvas = outcanvas;"(or something similar) in the code for the pywindow, which would give an output.

k AMC Past Events Typo-ish
Atoms789   3
N Jun 26, 2023 by LoreleiA
Summary of the problem: The past events slide for the AMC 8 competition say that students can participate in the "competitions" plural instead of singular.
Page URL: https://artofproblemsolving.com/contests/amc
Steps to reproduce:
1. Go to page URL
2. Scroll down to Past Events
3. Click Load More
4. Scroll down to the AMC 8 on January 18.
5. Notice the typo.
Expected behavior: The slide should say "competition" instead of "competitions"
Frequency: 100%
Additional information: In Past Events, AIME is referred to as a "competition" rather than "competitions" like the AMC 10/12. This shows that AoPS lists singular competitions as "the competition" rather than "the competitions."
