bug with the 4.0 catch base pro update (2nd post)

Hi, did anyone else get a bug with the 4.0 catch base pro update? I posted messages about it about 10 days ago, and Skandha tried to answer it, without success ... However, it is the update that generates the problem. I updated all the plugging independently, no problem. When I upgrade to version 4.0, here's what happens: Many customizations are lost: - the colors of the site; - the choice of fonts; - the layout of the home page: a "landscape" image appeared on the home page, with arrows on the side that did not exist before. - And also my header image has disappeared. ect ... and I can not go back unless I restore the site! I restored the site 2 times at an earlier date, and every time I go to version 4.0, it starts again. The only solution found is to stay at version 3.9.2. And to look for another theme, It's a shame really, not being able to solve this problem, on a paying theme and more !! Thank you for your answers,
