Can't activate plugin fatal error

Hi guys,

I’m getting error upon activating the plugin, below is the error detail:

Fatal error: Can’t inherit abstract function Aventura\Wprss\Core\Plugin\PluginInterface::getEventPrefix() (previously declared abstract in Aventura\Wprss\Core\Model\ModelInterface) in D:\Hosting\9437562\html\hombremag\wp-content\plugins\wp-rss-aggregator\includes\Aventura\Wprss\Core\Plugin\PluginAbstract.php on line 13

The plugin version is 4.8.1
Add-ons installed are:
-WP RSS Aggregator – Categories (Version 1.3 )
-WP RSS Aggregator – Excerpts and Thumbnails (Version 1.10)
-WP RSS Aggregator – Feed to Post (Version 3.6)
-WP RSS Aggregator – Full Text RSS (Feeds Version 1.3)
-WP RSS Aggregator – Keyword Filtering (Version 1.6)
-WP RSS Aggregator – Widget (version 1.1)

I have tried renaming the plugin and activated it again, but same error happens. I hope you can help me on this issue.

Thanks
