1.2 Update Messing Up Code

I updated this plugin today and then the code I had added through it stopped working. I noticed that it was adding “\” to escape some of the characters. Every time I saved, it would add them back. If I didn’t remove them, it kept adding more, so it would end up with \\\ or \\\\\.

I rolled back to version 1.1 and it works now, with all the “\” removed.

The code I was adding is on these pages:

But it’s not the code as it works with the last version.
