too much trouble for updates

Hello,
On several sites, I have problems of conflicts between iThemes sécurity and one or more other plugins. But I know that when I turn off ithème sécurity I have more problems. This is since you spent iThemes sécurity! it is very annoying if I suddenly I get an error reactive blank page “error” …
Other people have problems?
