Sorry frank, I had disabled bot (infolinks and autooptimize) and forgot to activate it back.
I have douns out tha the slider not functioning is due to W3TC(with minify disabled), so autooptimize is not the cause for the slider not working. I will contact W3tc support for a fix.
But I still have no success with getting the infolinks plugin at all with autooptimise enabled.
I have enabled both infolinks and optimise now. Thanks a lot Frank for your help.
