After that for example you go to Account Module and View the account you made instead of Bulk Actions it change to Email buttton. Please anyone help me. Thank yyou
Something tells me you’re not using the latest version in your branch. Please upgrade, I believe this has been fixed.
I used the latest version of SuiteCRM but stills it happens all the time i change in role management . 
thats really my problem i cant hide the delete button
I tried reproducing this but I can’t.
The delete button always shows for me, and in fact, no matter how hard I tried, I wasn’t able to restrict deletes with roles in y 7.11.4. Maybe I am doing something wrong…
You can try opening an issue with this on GitHub, or perhaps share some more details about how you set up security groups, roles, etc. so I can try exactly the same thing here…
Maybe it’s good also to share some screenshots here
and send us the links. Thanks
