Problem with version 2.07 and joomla 2.5.27

I'm trying to install version 2.07 with Joomla 2.5.27 and I've got this error message:
Parse error: syntax error, unexpected T_STATIC, expecting T_STRING or T_VARIABLE or '$' in /home/developp/public_html/administrator/components/com_joomailermailchimpintegration/helpers/html/bootstrap.php on line 47


This is how this problem happens. I installed Joomlamailer and I've got a message that it's been installed successfully. Then when I click on Component-Newsletter-List or report or campaign then I've got this error.

I've been using previous version with no problem at all. Then I've click to upgrade to latest version and since I've got this problem. I've uninstalled the component and make a fresh installation but got same problem. Need help. Thanks

Hello patmiami,

Which PHP version are you running on your server? At least 5.3.4 is required. PHP 5.3.4 was released in December 2011. If your host is using an even older version than that I don't know what they are doing all day long and you should consider to change the hosting company.

Kind regards,
Pete
