“getLocale() must be compatible” error when used with Eloquent

  • Hello,

    I am currently facing an issue when trying to use BackWPup and Eloquent version 9 (from the Illuminate/Database package) together in my WordPress site. The following error occurs:

    Fatal error: Declaration of Symfony\Component\Translation\TranslatorInterface::getLocale() must be compatible with Symfony\Contracts\Translation\LocaleAwareInterface::getLocale(): string in /var/www/html/wp-content/plugins/backwpup/vendor/symfony/translation/TranslatorInterface.php on line 69

    Here is the configuration of my environment:

    • BackWPup 4.0.2
    • illuminate/database 9.52.16
    • PHP 8.0.16
    • WordPress 6.4.2

    I am seeking any possible workaround or solution to this problem and would greatly appreciate any suggestions you might have.

    Additionally, I noticed a similar topic on the www.remarpro.com support forum, which appears to discuss a related issue, but it seems there was no clear resolution provided. Here is the link for reference:

    Thank you in advance for your help.

    I’ve managed to address the issue for now as follows:

    [/wp-content/plugins/backwpup/vendor/symfony/translation/TranslatorInterface.php:69]
public function getLocale();
↓
public function getLocale(): string;

    I believe the problem stems from using an older version of symfony/translation, so I’d appreciate it if you could update to a newer version during the next upgrade. It’s likely that the current version of symfony/translation integrated is below version 3, so I recommend upgrading to version 5 or higher.

    Thanks.

    Hello @kotatsuhal

    Thank you for reporting, this is a well know plugin conflict issue, will update you when I have something new!

    Hi @duongcuong96

    I have the same issue.
    In my case I use the symfony library in my theme as well. If I switch the theme, it seems to work again.
    The solution of @kotatsuhal did not work for me.

    The theme has the following packages and versions;

    symfony/intl                  v6.0.19 Provides a PHP replacement layer for the C intl 
    symfony/polyfill-ctype        v1.29.0 Symfony polyfill for ctype functions
    symfony/polyfill-intl-icu     v1.29.0 Symfony polyfill for intl's ICU-related data and classes
    symfony/polyfill-mbstring     v1.29.0 Symfony polyfill for the Mbstring extension
    symfony/polyfill-php81        v1.29.0 Symfony polyfill backporting some PHP 8.1+ features to lower PHP versions
    symfony/translation-contracts v3.0.2  Generic abstractions related to translation
    symfony/validator             v6.0.19 Provides tools to validate values

    Thanks for a fast solution

    Best, Daniel
