Will take another look to see if we can get 7.4 working on our site and post back there. * [linux4me2](https://wordpress.org/support/users/linux4me2/) * (@linux4me2) * [6 years, 1 month ago](https://wordpress.org/support/topic/updatescheck-php-and-php-7-4/#post-12760284) * You’re welcome! Good luck with it. Please post back with your results. I was planning on upgrading to PHP 7.4.x once they release a compatible version of IonCube for it. * I didn’t look at the code, but the errors PHP CodeSniffer found may be in there for backward compatibility, and not run with PHP >= 7.x, so they may not be an issue. * Thread Starter [hutman](https://wordpress.org/support/users/hutman/) * (@hutman) * [6 years, 1 month ago](https://wordpress.org/support/topic/updatescheck-php-and-php-7-4/#post-12760319) * The lines are in wp-content/plugins/mainwp/class/class-mainwp-utility.php * Changing lines 2126 and 2163 from: – in protected static function StrToNum( $Str, $Check, $Magic ) { * $Check += ord( $Str{$i} ); to $Check += ord( $Str[$i] ); * and – in protected static function CheckHash( $Hashnum ) { * $Re = $HashStr{$i}; to $Re = $HashStr[$i]; * Makes it work under php 7.4 (at least not emit errors and the return code is 0). Not sure about the validity of the fix for sure though, other than the suggestion based on the error output. * Plugin Support [Bogdan Rapaic](https://wordpress.org/support/users/bogdanrapaic/) * (@bogdanrapaic) * [6 years, 1 month ago](https://wordpress.org/support/topic/updatescheck-php-and-php-7-4/#post-12760338) * Hi [@hutman](https://wordpress.org/support/users/hutman/), since you have already opened a support ticket, we will continue there. * Hi [@linux4me2](https://wordpress.org/support/users/linux4me2/), PHP Compatibility Scanner is giving false positives since it doesn’t check code context. Deprecated functions are never executed on the unsupported version. * [linux4me2](https://wordpress.org/support/users/linux4me2/) * (@linux4me2) * [6 years, 1 month ago](https://wordpress.org/support/topic/updatescheck-php-and-php-7-4/#post-12760379) * Hi [@bogdanrapaic](https://wordpress.org/support/users/bogdanrapaic/) * Yes, I’ve noticed that with PHP CodeSniffer in the past.
