When we run the
setup:di:compile command we are seeing the following error. I would like to know what is going on here before I contact the extension developer.
I have searched for
MASK_FOR_HIDDEN in all files and it only exists in the file in the below error and also in one other file. Is this the problem? Do they need to be unique in both files?
[Exception] Notice: Constant MASK_FOR_HIDDEN_FIELDS already defined in /public_html/app/code/Magenest/SagePay/lib/classes/SagepayUtil.php on line 4
