Question

Hello, Guys!

I get this error, please help me solve it...

enter image description here

enter image description here

enter image description here

String value:

a:1:{s:14:"logotype_image";s:57:"/frontend/Alias/mysite/web/images/logo_grey.svg";}

And json_last_error = 4

The string value comes from the database.

How to fix it?

Was it helpful?

Solution

Magento change serialization from php to json in 2.1 version.

Looks like you have some data in database is not converted to proper format for some reason.

So, you need to convert co it manually to fix problem.
