Alidropship is usually installed onto built-in theme that plug developer provide.
But I want to install and make this plug working perfectly as if we install in developer theme.
1. Install plug onto existed website
2. check if this is working
3. fix error like variation text not showing and Buying is not working
4. Refer to Developer guide :
They answer like this
The plugin is not to be changed, it is not an open code. The built in themes however have fields for css script. If you plan using css, creating a child theme is recommended.
In general the developer can use our guides to install and set up the plugin
I bought builtin theme also
you can refer to this theme for this job
