Seeking insight: How have you managed WIRIS MathType/ChemType during a Moodle 4.5 upgrade?

Hi everyone,

We’re preparing for a Moodle 4.5 upgrade through OpenLMS, and I’ve run into a challenge regarding the WIRIS MathType/ChemType plugin. OpenLMS has flagged it as unapproved due to code precheck results, and they’ve confirmed that even the TinyMCE integration requires a signed waiver before installation or testing.

For context:

• Our STEM departments (Math, Science, Engineering, CIS) rely heavily on this tool for equation and chemical notation.
• There isn’t a truly comparable alternative that supports both MathType and ChemType.
• We’re now waiting for our institution’s security review before deciding whether to proceed with the waiver.

I’m hoping to hear from anyone else who’s dealt with this recently —

1. How did your institution handle the OpenLMS waiver requirement for WIRIS?
2. Did you decide to sign and continue using it, or remove it entirely?
3. If you removed it, what did you use as a functional replacement for equation/chemistry notation?
4. Did your testing in Moodle 4.5 reveal any issues or breakages with the plugin itself once installed?
5. How did you communicate or mitigate this change with your STEM faculty?

Any details or lessons learned would be incredibly valuable right now. Thanks in advance for any input!
