BL5.4.2
Getting red banner and this message after login, any suggestions?
GenericDataModel::__construct(): Implicitly marking parameter $engineDataModelSource as nullable is deprecated, the explicit nullable type must be used instead in GenericDataModel.php on line 12
TIA.
It looks like your Backlight installation isn’t compatible with the PHP version you’re using. You can change the PHP version in your host’s cpanel. If you’re using a lower version, that should resolve the issue. Alternatively, you could upgrade to the newest Backlight version.
Sometimes, website hosts update the PHP version on their own, without the user realizing it. This can cause your site to stop working unexpectedly.
Thanks Daniel,
slept on it, and this morning, all good.
