I have been reading some of posts on the support forum and there are many suggestions to make changes to .php .css files etc.
What happens when you update the plugin? Are these changes lost?
The theme I am using comes with an inbuilt Child Theme. Does this help?
I experimented with the Plugin on a test site some time ago and you were kind enough to change some settings to get it working with my theme. I have installed it again (on what will be the live site) with the intention of moving forward but of course I had to copy the files you changed over to the new site. I don't want to have to do this if the plugin is updated.
Sorry I am not a programmer or an expert on WordPress.
