WebMO Support Forum

My computational chemistry students report that the "Build Molecule" window is not loading. Most are using Chrome on MacOS, and it works fine on Safari.

Sample window is attached.

Bob,

This seems very unexpected as I primarily test / use Mac OS + Chrome on a daily basis. A few questions:

(1) What WebMO version?
(2) Does this work fine when accessing the WebMO Demo Server using these same Macs?
(3) Make sure to clear all browser cache, etc., as this when problems occur, this is often the issue.
(4) Finally, if issues persist, check the browser Javascript console and report back and errors that you see.

I can confirm that we're seeing this as well. This is the error message from Chrome:

moledit_js-0.js:1826 Uncaught TypeError: Failed to execute 'uniformMatrix4fv' on 'WebGLRenderingContext': The provided float value is non-finite.

This is Chrome 128.0.6613.85. We're running WebMO 23.0.017e. Firefox works without issue. This appears to be a broader issue with Chromium in general, see for example this post from the ESRI forum last week.

Just tried this with fully updated Chrome (now 128.0.6613.114 -- a bit higher!) and it works fine, also on Mac OS X. Maybe Chrome introduce a bug that they have now resolved?

Thanks for the response. I've updated to Chrome 128.0.6613.114 and it's now working under that version. The most recent version of Edge (128.0.2739.42) is still broken.
