@all
If you guys still struggling with this issue, I would suggest you to connect to your back end using Filezilla or any other way you prefer, Then go to that file in the error message and change code in line 236 where with each arument you can specify it to me array like array_merge= ((array) $A , (array)$B)
this solved my problem I took me 10 minute to figure this out( although this is temp fix) and don’t know why there was no clear reply here from support.
Thanks
