Forum Here we go again, upgrade errors!

[محروم.كوم]

I've tried upgrading tonite from 3.8.4 to v4.0 and come up with this error

Parse error: syntax error, unexpected T_STATIC, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in /homepages/28/d166227607/htdocs/studio595/includes/class_core.php on line 1380

Now then I've done a search and tried installing a .htaccess file to overcome the 1and1 server issues that allegedly exist, even tho I haven't had these problems before, and when I install the .htaccess file I then get this message -

Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, [email protected] and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

Some help would be great please, as at present I have no idea at all! __DEFINE_LIKE_SHARE__
