 * Hi.
 * I’m having[ ](https://www.b2bappointmentsetting.com/)problems with my site since
   I upgraded my PHP version with my webhost.
 * The front end works, but looks completely wrong, and I’m getting the following
   error when I try to access the backend:
 * Warning: “continue” targeting switch is equivalent to “break”. Did you mean to
   use “continue 2”? in /homepages/22/d729427755/htdocs/wp-content/plugins/jupiter-
   donut/includes/helpers/minify/src/Minifier.php on line 227
 * Warning: Cannot modify header information – headers already sent by (output started

   helpers/minify/src/Minifier.php:227) in /homepages/22/d729427755/htdocs/wp-includes/
   pluggable.php on line 1265

 * What do I need to do?

 * 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, 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 (consult your hosting
   provider’s documentation for specifics on these), 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 (theme
   functions can interfere like plugins).
