Ok so i kinda figured it out. The problem is jQuery version – it works splendid on latest version, but unfortunely not many of templates uses it. I’ve used vTicker script instead, since i didn’t really had time for debugging.
Don’t bother looking into NovelLight + your plugin, that theme is a mess and seems like author don’t really care about fixing his theme. I’m already making my project on different template.
Would be nice tho, if you would give info in FAQ/General info about minimum jQuery version.
