Error due to outdated PHP version

If you try to install ConvertPlug on servers running outdated PHP version, you might see an error like this –

Plugin could not be activated because it triggered a fatal error.
Parse error: syntax error, unexpected T_PAAMAYIM_NEKUDOTAYIM in /wp-content/plugins/convertplug/framework/Smile_Framework.php on line 73

OR

Fatal error: Using $this when not in object context in /(...)/convertplug/admin/contacts/views/cp-paginator.php on line 70

Reason –

If your server is running outdated PHP, this error is common as they uses double colon ( :: ) for accessing static object. WordPress needs PHP 5.6 or greater version installed on the server as specified here.

Solution –

Please contact your Web Host for help and ask them to update PHP, especially because 5.4 has come to “End Of Life”.
