The stylesheet was embedded into the template itself, it was not coming from the plugin. That is not how it should be.
Anyways I might figured out what is causing the issue. There is one functions that prints the stylesheets to the header, I think that might be blocked by an action or filter in the template.
I cant edit the files however with the ftp account nor the admin account you provided. Can you please upgrade the temp ftp account to make me able to modify the search files?Best,
