Apache crash uninstall modsecurity

I am getting 403 errors on my webiste with mod security enabled.  I wanted to uninstall mod security to check if the 403 errors stop.  But apache will not restart after uninstall modsec.   Installing mod security again will bring apache back.  I would like to disable mod security to verify if it is the source of 403 error.

Your stiation is good.  At mine, Apache crash when i have installed Mod-Security. Also Apache rebuilt doesn't work.
