Thanks a lot for your help.
I try to understand what you’re talking about cause I m completely new on wp and that kind of thing!And my english is not excellent(I m french)!
I’ve backed up everything yesterday evening.
I’m gonna desactivate all plugins.

What does”switching to the unedited default, core-bundled Theme (such as Twenty Twelve, Twenty Thirteen or Twenty Fourteen) for a moment using the WP dashboard to rule out any theme-specific issue.”means?

Thanks again and have a nice day.
