All dropdown menus are empty, map display gone

I let the window sit for a few days, and when I came back all the menus were completely empty and the map missing despite reloading the page several times and opening it again in a new tab.

Hello, which browser are you using? Does the page work correctly if you open it in a private window?

My best guess would be it's a cache issue after having the page open for a long time, though I have no idea why this would happen. Try to reload the page (in a regular window, not private) after disabling cache: Right click somewhere in the page > Inspect > Network tab > check Disable cache, and reload the page (these steps should be similar both for Chrome and Firefox).

Let me know if this works. If not, please send me what's written in the Console tab of the dev tools just after reloading the page (right click > Inspect > Console tab).

I'm using Firefox and it didn't work in a private window, nor in any new tab or window after disabling the cache. Here's what's going on in the console.

So it seems that Firefox fails to find the WebGL driver. What's your PC configuration (CPU, GPU, OS)? Did any update happen before the website was broken?

Have you tried if other apps/websites that rely on WebGL work? You can for example check if this website correctly displays pictures/animations or a big error message.

If WebGL fails on other websites as well, a few things you can try:

• Update your GPU drivers.
• Be sure to have the latest up to date version of Firefox.
• Enter about:support in the address bar and look for the Graphics section. Check there if the rows labelled WebGL 1/2 Driver Version and WebGL 1/2 Driver Renderer are correctly defined, i.e. are set to something like OpenGL ES 3.0.0 (ANGLE 2.1.19739 ...) and Google Inc. (AMD) -- ANGLE ... (will be different depending on your PC's specs). Check also if your GPU is correctly detected (GPU #1 subsection, should have a Driver row).

Let me know of the results.

I'm on windows 10 and i dont think any updates have happened for it? The website you linked seems to work fine. Updating firefox seems to have fixed it tho, thanks!

Glad you got it fixed! I'm not sure what caused this bug though. I'll close the issue, don't hesitate to re-open it if the it happens again.

[SeoReadeHenn]

Bad news, it's broken again, and other applications that use webgl don't work either. I updated my graphics drivers which didnt fix it, and things seem to all be as they should be in about:support (also it seems i cant reopen the issue)

This is a problem beyond the MGA website then, probably some misconfiguration on firefox.

Is the output in the dev console the same as in the previous occurence of the bug? Or is it a different error message? (please send me what's in the console in that case).

What I can suggest is go to about:config (this will show a warning page, press on accept the risk and continue). In the search bar search for:

• webgl.disabled and make sure it's set to false
• webgl.force-enabled and make sure it's set to true
• webgl.enable-webgl2 and make sure it's true

Another thing I would try is clearing all saved data in firefox settings: cookies and site data, temporary cached files and pages, site settings.

If none of this works the only thing left I can suggest is doing a fresh reinstall of firefox (save your bookmarks or whatever you need before).

Another thing you can try is to set webgl.disable-angle to true (don't forget to restart firefox afterwards).
