 * Hi,
 * I upgraded the site version from Php5.5 to Php7.2. But some add-ons like W3 Total
   Cache prevented the customization panel from opening. I am using W3 Total Cache
   version 0.9.7.
    Is it possible to make php7.2 compliant without removing and 
   reinstalling the program?
 * Regards…
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fproblem-upgrading-from-php5-5-to-php7-2%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hi Gokh,
    We’d faced the similar issue while upgrading from PHP 5.6 to 7, which
   we resolved by enabling required extensions and other stuffs.

 * Hi raagsinghdelhi,
 * There is no problem with Php 7.1, but there is a problem with Php 7.2.

 * _ W3 Total Cache prevented the customization panel from opening._
 * So i am on the same page, the customization panel is the area in Admin page when
   you can customize your theme in realtime? If so does this imply you are caching
   logged in users — specifically the administrator?
 * For me w3tc works perfectly in 7.2 but then i am using the community build..but
   if this problem persists i can install the official 0.9.7 and see what you might
   be seeing in 7.2.

 * In W3TC 7.2 the customizer panel opens. But there is no screen display.
