HI Mehtaz - no this isn't the solution.
The Firewall is not striping code. I can add code to After <body>, Before </body>, Custom CSS, Custom Javascript etc.
What happens is when I try to save the template settings with code in Before </head> I get the error:
Error
Error: undefined
See screen shot here: https://www.dropbox.com/scl/fi/t9axmcdkeqg6st4u8i2c5/Capture.JPG?rlkey=9tezgjog6gaoz29qc40k2m0bb&st=gknnx51r&dl=0
As long as Before </head> is empty it's o.k. - the minute I try to add any code here I get the error.
This works fine with Helix 3 - but I'm trying to update sites to Helix Ultimate.
PLease let me know when this has been fixed.
Thanks,
Syd
