Two errors, not sure what they mean

[crashfirephoenix]

Hi,
I am on SMF 2.0.15, PHP 7 and using the Reseller theme. I attached my mod list.

In my error log I am seeing the following two errors pop up. I'm not sure what these could be in relation to...does anyone have any ideas?

You will have to get an update for that mod to run properly on php7

Do you know which mod might be causing the errors? I'm not sure from the files

It's a bug in 2.0.x on PHP 7 in the audio CAPTCHA.

The second error is also an issue in core SMF but not sure how it's caused yet.
