Hello, I've been using the plugin "football pool" and all good, but when you upgrade to the latest version I get the following error:
The plugin could not be activated because it triggered a fatal error.
Fatal error: Call to undefined method DateTime::getTimestamp() in /.../.../public_html/wp-content/plugins/football-pool/classes/class-football-pool.php on line 64
Can you tell me it is because this error? If not, could someone give me the pre-final version to work with this plugin?
