# Fatal Error when activating version 4.10

 * The plugin couldn’t be activated and triggered a fatal error message saying:
 * Fatal error: Can’t inherit abstract function Aventura\Wprss\Core\Model\Event\
   EventInterface::getData() (previously declared abstract in Aventura\Wprss\Core\
   DataObjectInterface) in /home/wordpress/webdata/wp-content/plugins/wp-rss-aggregator/
   includes/Aventura/Wprss/Core/Model/Event/EventAbstract.php on line 11
 * I’ve tried versions 4.9 and 4.9.1, they both worked fine when activating the 
   plugin. The version of WordPress used is 4.7.

 * Hi [@ellavore](https://wordpress.org/support/users/ellavore/)
 * The error you have here is similar to the one explained [here](https://docs.wprssaggregator.com/solving-errors/#fatal-error-cant-inherit-abstract-function).
 * Can you please check which PHP version you have at your site? You can see it 
   from your [System Information](https://docs.wprssaggregator.com/error-logs-and-system-information/)
   on your Debugging page.

 * Hi [@erricgunawan](https://wordpress.org/support/users/erricgunawan/)
 * I can’t access the debugging page if I can’t activate the plugin to check it.
