Hi @gmilazzo,

Are you using 3rd-party modules?

Which version of PHP has your server?

[gmilazzo]

Are you using 3rd-party modules? yes doing another clean install with no 3rd party

Which version of PHP has your server? 7.0 & tried with 7.1 I will see if works after this next clean install or not will keep you posted

[gmilazzo]

Pleased to announce it's not magento it was a 3rd party theme and they are working on resolving the issue
