 * I’ve installed the plugin and it was working fine. Then I had to uninstall it
   and when I now try to reinstall it I get a fatal error upon activation:
 * > Fatal error: Can’t inherit abstract function Aventura\Wprss\Core\Model\Event\
   > EventInterface::getData() (previously declared abstract in Aventura\Wprss\Core\
   > DataObjectInterface) in /var/www/html/asf/wp-content/plugins/wp-rss-aggregator/
   > includes/Aventura/Wprss/Core/Model/Event/EventAbstract.php on line 11
 * How can I activate the plugin? Is there any rows in the database I need to remove?
 * Best regards
    /Kjell

 * Hi Kjell,
 * The error you have is explained [here](https://docs.wprssaggregator.com/solving-errors/#fatal-error-cant-inherit-abstract-function).
 * In short, it could happen because of an outdated version of PHP (lower than PHP
   5.3), which is a requirement for WP RSS Aggregator.
 * Did you re-install the plugin on a different site/server/host?
 * Also, could you please confirm which PHP version run on your current host/server?

 * Hi,
    Yup, I’ve got 5.3.3 and I thought that it would be sufficient for running
   the site. I’ll have to look into updating PHP.
 * I guess I never had it running on that server, sorry for misinforming you…
 * Thanks a lot!

 * You’re welcome, Kjell.
 * No worries. The most important thing is you got that and hopefully you can get
   the plugin running once you update your PHP version.
 * Let us know if you have more questions.
 * Also, once you can get it running, if you like our products or the quality of
   our support, please consider leaving a positive review [here](https://wordpress.org/support/plugin/wp-rss-aggregator/reviews/).
 * It would be greatly appreciated by the whole team.
 * Have a great day!
