Thanks again!
I have JTC working but Maintenance mode still don´t show up as expected. In admin it says it´s enabled/activated.
I also started a topic on Blooms support forum located at elegantthemes.com + mailed authors of WPEasycart. No answer yet.
I will have a look at BPS troubleshooting links and see if I can find anything there that I have missed.
