Code:A PHP Error was encountered Severity: Compile Error Message: Declaration of Symfony\Component\Translation\TranslatorInterface::getLocale() must be compatible with Symfony\Contracts\Translation\LocaleAwareInterface::getLocale(): string Filename: translation/TranslatorInterface.php Line Number: 69 Backtrace:
instead of just copying 3.1.5 atop the existing install and upgrading, tried wiping all folders except the "uploads" and config...and reupping 3.1.5 and all seems to work... seems odd though, would remnant files from older installs and not overwritten by 3.1.5 cause issues? seems so.
