 * Hello all,
 * First time using WordPress and while it’s great so far, I’m trying to add plugins
   to my page and keep getting this consistent error.
 * Installation failed: <!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Strict//EN”“
   [http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd”&gt](http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd”&gt);

 * Internal server errors (error 500) are often caused by plugin or theme function
   conflicts, so if you have access to your admin panel, try deactivating all plugins.
   If you don’t have access to your admin panel, try [manually resetting your plugins](https://wordpress.org/support/article/faq-troubleshooting/#how-to-deactivate-all-plugins-when-not-able-to-access-the-administrative-menus)(
   no Dashboard access required). If that resolves the issue, reactivate each one
   individually until you find the cause.
 * If that does not resolve the issue, try switching to the default theme for your
   version of WordPress to rule-out a theme-specific issue. If you don’t have access
   to your admin panel, access your server via [SFTP or FTP](https://wordpress.org/support/article/ftp-clients/),
   or a file manager in your hosting account’s control panel, navigate to `/wp-content/
   themes/` and rename the directory of your currently active theme. This will force
   the default theme to activate and hopefully rule-out a theme-specific issue.
 * If that does not resolve the issue, it’s possible that a `.htaccess` rule could
   be the source of the problem. To check for this, access your server via SFTP 
   or FTP, or a file manager in your hosting account’s control panel, and rename
   the `.htaccess` file. If you can’t find a `.htaccess` file, make sure that you
   have set your SFTP or FTP client to view invisible files.
 * If you weren’t able to resolve the issue by either resetting your plugins and
   theme or renaming your `.htaccess` file, we may be able to help, but we’ll need
   a more detailed error message. Internal server errors are usually described in
   more detail in the server error log. If you have access to your server error 
   log, generate the error again, note the date and time, then immediately check
   your server error log for any errors that occurred during that time period. If
   you don’t have access to your server error log, ask your hosting provider to 
   look for you.
