Hello out there? No backend access! Giving up…

the pages and posts are in your database accessible in phpmyadmin area of your webhosting account
the media files (uploads), themes and plugins accessible in your webhosting

do you have access to your webhosting control panel?
if yes, find the file manager to delete the themes or plugins that are causing trouble in WP Content folder.
be sure to leave at least one theme in your file manager (i.e. twenty sixteen)

if you are not sure how to access your control panel and file manager —contact the support team for your webhosting

do you have a backup of your website database and files from before the problem happened?
does your webhost have a backup copy of your website database and files from before the problem happened?

Thank you contentiskey!
I do have access to the webhosting control panel. Backup is there, but I don’t know the steps of implementing it. Kind of afraid to do anything now.
We use go daddy and plesk. The host is risen phoenix and the guy I emailed said he doesn’t know much about web development and he’d ask his partner at Bubtown. I am a non-professional (obviously) who is simply helping out a small business -veterinarian in NJ.
I also have ftp access.
In the new installation, I downloaded theme twentytwelve. But when I log on to plesk and look at the themes, it’s not there. I refresh and clear cache and still not there, so I’m hesitant and think i must be doing something wrong.
The website is oldwickanimalhospital.com
Again, thank you for answering – I’m going to see what I can do now.

I don’t use plesk but ftp access will be fine for checking on your WP Content folders
-Can you share a list of the themes currently in your WP Content folder
-Can you share a list of plugins currently in your WP Content folder

Is your webhost “Risen Phoenix” or GoDaddy?

I can see the website.

Can you get to your database?
I want to understand some information that is set up in the Options table.

Is your WP Content folder in the root of your website or in a sub-folder?

Hello, Contentiskey,
I had given up on finding a solution here and didn’t see this til now. Thank you again.
Yes I can get to the databases but I have no idea how to extract info. The backups are done daily, so if it backs up the themes and plugins, then the corrupted files are there? I don’t know how that works.
Anyway, all the wordpress stuff is in public/wordpress/
I created two new installations of wordpress, eventually deleted one of them, but there’s also public/wordpress_0/ now.
Good question about the host. It’s GoDaddy (NOT my choice – all done before I volunteered to help out this veterinarian and her office manaager) and where risenphoenix comes in I don’t know.
The office manager has decided we may go with a commercial theme. She and I are going to talk next week while we wait for risenphoenix to fix or some education from this support forum to help me straighten it out.
The theme I’m trying to use for wordpress_0 is twentyfifteen. WordPress/ theme is Nirvana and it will not update. The wordpress_0 site looked acceptable for a while, but now the theme is MIA!.
Thank you,
Gail
