M2 site copy - Theme error

[Andy_Acute]

Hi all -

I have our site running fine on our hosting. Our hosting is split into two separate instances of Magento 2 and I've copied the files, exported and imported the database so that I use this copied version for staging and developing.
The problem is that I'm getting an error (in the reports) containing the below:

It's obviously connected with the theme, but I can't figure out how to fix it.

As far as I am aware, I have copied all third party modules and enabled them using SSH.

Any ideas anyone?

Many thanks in advance

Andy

Hello @Andy_Acute ,

Go to DB and check theme table

and check type column into db

It should be value 0 if it is one 1 then change to 0

and do cache flush and check it

If works then mark as solution

Hi @Andy_Acute ,

Go to your core_config_data table and search the column path for design/theme/theme_id

SELECT * FROM core_config_data WHERE path = "design/theme/theme_id"

and replace your default theme id in it.

Flush your cache using php bin/magento cache:flush
