Looks like the whole directory is gone.
At this point, might as well upgrade to 4.3.1, which will of course fix that as well as any other missing core files: https://codex.wordpress.org/Upgrading_WordPress_Extended
When I visit http://amavqroo.mx/wp-admin/ I’m brought to a 403 error page.
Upgrading will certainly help to resolve most any issue and should definitely be performed. There may be alternative troubleshooting steps you could take to get the website up and running in the meantime.
403 errors have 3 most common causes
1. Permissions issues. All files should the SuPHP friendly permissions of 644 and folders should be 755. This is true for any Linux based host. You can contact your hosting provider and request they perform a script to fix permissions.
2. No index.php file. Check the directory of your WordPress installation and ensure that a index.php file exist. If it does not replace it with a default index.php file from the latest zip from https://wordpress.org/download/
3. Errors or conflicts with code found in the .htaccess file. This is a file that makes changes to the web server configuration and effects the directory it is stored in and all sub directories. Rename the .htaccess file .htacess.deactive and create a new .htaccess file. Then add the following code:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
If you are not sure how to make the .htaccess changes yourself a supportive host may be able to assist you. This is typically out of scope for most web hosting companies, but you can always ask.
Also you can replace directories like wp-admin and wp-includes with copies from https://wordpress.org/news/category/releases/
I recommend renaming the current wp-admin and wp-includes directories before adding the default ones.
Hope you have found this helpful! Thanks for reading!
To be honest though, take the chance to upgrade. At 3.2.1, you’re over 4 years out of date, with a lot of publicly known security vulnerabilities.
