I'm helping someone that has no technical experiences with their WordPress site, and I realized he may have accidentally set it up as a multisite.
My question is if I don't want to go through all the trouble of changing the site back to a regular WordPress site, can I just treat and use the site as a regular WordPress site? Or will there be any technical difficulties later on? (the site just displays some content and can put items in shopping cart to buy them)
And since it's a multisite and I only have admin power and not super admin, to install plugins I would have to either ask for access to the super admin account or have the person install the plugins for me, right?
Lastly, how would I access and change the
wp-content/ files to customize (css/html/js) the templates myself? Do I just download Filezilla to grab the files and change them and upload them back? Or is there a better way to do this?
And would I need super admin power to do this and what additional information do I need to set up the Filezilla besides the site url, my admin account and password?
Sorry for so many questions on here, please let me know if you need any additional information.
