I have modified the Edit and Details layouts on LEADS but although i save and deploy the layouts do not change when you open a LEAD?
I hove successfully modified the layouts for Contacts and for Accounts.
(latest SuiteCRM running on Ubuntu with the MySQl database)
check the permissions are set correctly on your custom folder
Something strange happened. I had the sub menus set to Tabs rather than Panel. I changed them back to panel. I went to LEADS and the correct layout was shown, whereas it was not showing the correct layout before. Weird. I will try changing it back to Tabs later today and see if it reverts to the wrong layout of fields.
