 * Hi!
    I just upgraded to Visual Composer 4.12.1 and noticed problems with some
   of the VC plugins. Once I deactivate Autoptimize it all works fine. As I need
   the plugins, this is for me the best solution for now. Thought I still let you
   know about the problem, as there might be more people having it…

 * thanks for reporting hannawp!
 * some questions;
    * what VC plugins were broken (and how)? * what JS errors did
   you see on your browser’s console? * what is your AO configuration? * did you
   try disablinb only JS optimization (the problem is 99% sure a JS-one, so you 
   could keep CSS optimization)? * did you try the troubleshooting-tips in [the FAQ](https://wordpress.org/plugins/autoptimize/faq/)?*
   did you contact VC-team as well? any idea what got changed?
 * I’ll be happy to troubleshoot this with you 🙂

 * Hi
 * I`ve got the same problem.
    When I start composer I can see only preloader.

 * hi go2air;
    this seems like a problem when a logged in user tries to use VC to
   do the actual pagebulding. have a look at [the FAQ](https://wordpress.org/plugins/autoptimize/faq),
   which explains how you can disable AO for logged in users (typically the context
   in which visual pagebuilding is done).
 * hope this helps,
    frank
