can i delete unused themes

Some of those themes might simply need updates to satisfy the Wordfence scans, and yes, I sometimes just remove and re-install a plugin to get rid of those “warnings”. Also, keep in mind that some plugins occasionally get “quiet updates” that will clear in a few days after an actual update notice has been sent out and acted upon.

Can I just delete those wordpress themes [ I don’t even use] from the page within wordpress under appearance, themes…and should I also delete those theme directories from my Bluehost server…?

You need to have at least Twenty Twelve there for possible troubleshooting at any given time, and you might as well have Twenty Thirteen since it is the latest default theme. What I would do there is to delete all themes other than the one/s you actually need…and keep in mind that your custom theme will need its parent if it happens to be a Child Theme. But after deleting all the ones you do not need in order to keep the site running, re-install fresh copies of Twenty Twelve and Twenty Thirteen…and no, you will have have to delete any theme at the server since the dashboard action will take care of that.

Thank you. Is there anywhere to tell if my custom theme is a child of a parent theme? I don’t think so i’m pretty sure I asked him before and he said he created it from scratch, but he does not return any communications I send to him regarding my site anymore. So I am on my own. But if for some chance it was a child and I deleted 2012 and then reinstalled it would my site be down or not function properly until it was reinstalled and would any updates to 2012 (if parent) mess anything up in the child theme (my website).

I just look at my style.css and this is what he put at the top

‘/*
Theme Name: chromehorse
Theme URI:
Description: Custom Theme Chromehorse
Version: 1.0
Author: Buildwordpress.co
Author URI: https://buildwordpress.co/
Tags: fixed width, right sidebar, two columns, valid XHTML, widgets
*/’

So there is no indication that this would be a child theme, at least from this description; unless he just didn’t title it “child” but hopefully he would not have been that not detail oriented.

That’s not a child theme.

But if for some chance it was a child and I deleted 2012 and then reinstalled it would my site be down or not function properly until it was reinstalled…

Even though that is no longer a concern here, it might some day be helpful for you to know an activated Child Theme will have a line beside it there on the Dashboard saying, “This child theme requires its parent theme, (whatever theme).” And yes, things would certainly be a mess without one! But overall, never panic. If your Dashboard ever turns completely white and your site looks like a text-only BB from the ’80s, a fix is still possibly just a few clicks away via FTP/SFTP.

thank you i have deleted the themes that I don’t use. And sucuri is helping me get my site clean and protected. Yesterday when doing a search for my site in the search results there was red text under my listing saying “warning dangerous downloads”!! Does anyone know how long that will stay there or how i get it to stop saying that
