After “Analyze” returned 2 different results

Hi,

I tried to create a child them for this theme
https://wordpress.org/themes/seos-magazine/

After clicking “Analyze”,

The first time it returned:

The theme “Seos Magazine” generated unexpected PHP debug output.

I have AVH Extended Categories Widgets plugin installed on my site.

But the second time around it returned:

This theme appears OK to use as a Child theme.

This theme loads additional stylesheets after the style.css file:
(a list of things here)

I went ahead and created a child theme the 2nd time but not sure if it’s safe to use it under such circumstances.

After verifying the child theme make sure it looks right at frontend, I analyze it (the parent theme) the third time and it reverted to the first time result.

Thank you.
