Fatal error in plg_modulelinks

Hi,
Our host has upgraded their servers to newest php version and now i have a fatal error:

Fatal error: Class 'JParameter' not found in /var/www/vhosts/5804.linux10.testsider.dk/httpdocs/plugins/system/plg_gkmodulelinks/plg_gkmodulelinks.php on line 26

Joomla is version 2.5

Any suggestion? Thanks

Kind regards.

Hi

The only way now is to rename /plugins/system/plg_gkmodulelinks/plg_gkmodulelinks.php to /plugins/system/_plg_gkmodulelinks/plg_gkmodulelinks.php or uninstall this plugin if You can still use joomla panel.

This problem is fixed in Joomla 3 version of this plugin, but not in this old one.
