I have posted a question in SU about a software freezing my computer but its freezing only when I run WP and a specific WP plugin.

The question is initially posted in SU but it belongs to WordPress site too (because of the issue with WP).

If I have a question like this in future what should I do? What's the best SE site to post the question to?

Let me explain it a little more:
I am developing a WP site locally. Visual Composer and GravityForms are the two plugins in question here.
I have put a GravityForms forms on a page and the same page's content is created using Visual Composer.
When I install new version of the theme and loads the page (with that form on it) it hangs WAMP/Apache/My PC and I have no option but to end the WAMP process via task manager.

• The same page loads fine when I use older version of the theme.
