# PHP upgrade causing issues for BackWPup

 * I have been using BackWPup for 4 years and never had a problem until I upgraded
   from PHP 7.3 to PHP 7.4 last week.
    After the upgrade I was no longer able to
   login to wp-admin. I disabled the plugins one at a time using ftp and when I 
   disabled the BackWPup plugin I was able to access wp-admin again. I deleted BackWPup
   plugin and reinstalled it again hoping that would solve the problem but it didn’t.
   BackWPup seems to make my wp-admin login inaccessible. Do you know what may be
   causing this?

 * Hello [@kboroumand](https://wordpress.org/support/users/kboroumand/)
    I guess
   there is a missing PHP extension after you switched to PHP 7.4, to make sure 
   it all works, please enable all extensions as you already enabled on PHP 7.3 
   In case it still does not works, please enable debug display so you will know
   what issue you got, please copy the error text then give it to me too. Thank 
   you!

 * Hello, and thank you for your response.
    My host is a Linux Centos 7 and I just
   realized I have to install PHP-FPM package in order to set the system default
   PHP to 7.4 So even though the package handler in my .htaccess file points to 
   7.4 :
 *     ```
       <IfModule mime_module>
         AddHandler application/x-httpd-ea-php74 .php .php7 .phtml
       </IfModule>
       ```
   
 * The default PHP version is still set to 7.3
    I will install the PHP-FPM package
   make 7.4 the default and try again over the weekend. Will let you know if that
   fixes it. Thanks.

    Thanks, let me
   know in case you have fixed the issue ^^ This should not be related to BackWPUp
   but rather than the server-side issue ^^ Btw, In case you find BackWPUp is useful
   for you, we would really appreciate it if you leave a positive review and rating.
   This would encourage us to develop new free features and provide free support

   Thank you so much and have a great weekend!
