Blank Page at Checkout

[Zippkits]

Help!
Getting a blank page at checkout!
No updates or major changes. I did change some wording in a shipping module a few days ago, but this showed up today.
I disabled the module just in case, but still get a blank page.
No issues in admin logs.
Help!

"Blank page" implies that there's a myDEBUG*.log file present in the site's /logs directory that identifies the source of the issue.

Thanks.
I was able to restore the module files from a week ago. Not sure what happened, but it is all good now.
