I've just re-tooled the Theme Forest patch in SLP v3.7 I am working on for release next week. Since I've been told by Envato that they are aware of the bug but that not every theme author uses wptreats_formatter() and instead "baked their own" "bug-function" I had to take another tact. SLP v3.6.2 fixes SOME Theme Forest themes but not the "homemade bug function" themes.
Sadly, Envato also refuses to release any themes that are known to be broken so that I can test my patches. Thus, I need to rely on the Theme Forest customers here to do my testing (or send me their zippped theme file). So... if you have open HTML on a Theme Forest them and want to test SLP 3.7 beta please contact me at http://www.charlestonsw.com/mindset/contact-us/ and I'll send a pre-release copy of SLP 3.7 to test.
Hopefully some new creative "cleansing" of the newline characters in the perfectly-valid SLP HTML output will stop the Theme Forest bug from rearing its ugly head in the SLP output.
