I am getting the error on a new install on my hosting provider:

Internal Server Error

Fatal error: PHP Startup: Unable to load dynamic library '/usr/lib/php/extensions/no-debug-non-zts-20090626/timezonedb.so' - /usr/lib/php/extensions/no-debug-non-zts-20090626/timezonedb.so: cannot open shared object file: No such file or directory

Any ideas?

Thanks!
