 Hi guys after moving my site to a new isp an error occured after moving the site. See below.

[Tue Nov 11 16:52:09 2014] [error] [client 217.122.98.177] [host www.kagia.nl] Backend fatal error: PHP Fatal error: Call to undefined function MaxMind\\Db\\Reader\\bcadd() in /home/deb83540n2/domains/kagia.nl/public_html/plugins/system/akgeoip/lib/vendor/maxmind-db/reader/src/MaxMind/Db/Reader/Decoder.php on line 252\n, referer: http://www.kagia.nl/administrator/

The famous blank screen occurs when administrator is called.
Any idea how to solve this????

If I disable the main.php in /domains/kagia.nl/public_html/plugins/system/admintools/admintools administrator screen is working and everything is oke.
Also installed admintool pro twice but when main.php is enabled administrator screen is white and error as mentioned above occurs.

Please download and install the Akeeba Geo-IP Provider Plugin from https://www.akeebabackup.com/download/akgeoip/1-0-5/plg_system_akgeoip-1-0-5-zip.html. You may also need to update the Geo-IP data from the Admin Tools screen.
