 * Hi Crew,
 * First of all many thanks for this great piece of software!
    When I changed the
   php version from 7.1 to 7.2 or 7.3 I got this error (below), so I reverted back
   to 7.1, which isn’t a good idea because of security issues
 * Warning: Use of undefined constant ?UPDRAFTPLUS_NO_BINZIP? – assumed ‘?UPDRAFTPLUS_NO_BINZIP?’(
   this will throw an Error in a future version of PHP) in /home/reggaevi/public_html/
   wp-config.php on line 36
 * Any ideas?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fphp-upgrade-error%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hi,
 * This error indicates that you have the ‘UPDRAFTPLUS_NO_BINZIP’ constant defined
   in your wp-config file, but likely the define is not set up correctly.
 * Please could you check your wp-config file and check line 36. You should see 
   something that looks like the following:
 * `define('UPDRAFTPLUS_NO_BINZIP', true);`
 * Please replace what is in the file with the above line (even if they appear the
   same).
    This should stop the warning.
