Hi,

I'm trying to understand where the Math extension writes temporary files as I want to check the folder permissions. Can anyone point me in the right direction?

I am basically trying to solve an issue where the rendering fails and when I check Math Status in the special pages on my wiki it shows:

### MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools)

Running backend tests for rendering mode *MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools)*.

Test *Rendering the input "x^2+\text{a sample Text}"* succeeded.

Test *Comparing to the reference rendering* succeeded.

Test *Rendering of a+b in plain MathML mode* succeeded.

Test *Checking the presence of '+' in the MathML output* succeeded.

Test *Comparing the generated SVG with the reference* failed.

Test *Checking if MathML input is supported* succeeded.

Test *Rendering Presentation MathML sample* failed.

Test *Checking if the link to SVG image is correct* failed.

Backend tests for rendering mode *MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools)* completed.

As you can see the first failure is where it tries to compare the generated SVG with the reference. I am curious as to whether it is unable to save the generated SVG to the temporary directory.

Hope someone can help me out as I've been trying to solve this for several days now.

Many thanks in advance.
