LinkEX

Hello,
First of all thank you for this fantastic script. I`m using it from 2007 and I never had a bigger problems. Most
solutions I here on forums.

Some weeks ago I upgraded my all my linkex instances to newest 20090603.

Today I noticed problems with PageRank Test, when I it there is only blank page and error logs give:
PHP Fatal error: Class 'PageRank' not found in /home/www/er.com/www/index.php on line 6778
PHP Fatal error: Class 'PageRank' not found in /home/www/er.com/www/index.php on line 6778

Few moments later I noticed another (during mass adding links):
PHP Warning: array_reverse() [<a href='function.array-reverse'>function.array-reverse</a>]: The argument
should be an array in /home/www/er.com/www/index.php on line 2227
PHP Warning: array_reverse() [<a href='function.array-reverse'>function.array-reverse</a>]: The argument
should be an array in /home/www/er.com/www/index.php on line 2227

My installation Freebsd 6, Apache 2.2
PHP 5.2.8 with Suhosin-Patch 0.9.6.3

$cat /usr/local/etc/php/extensions.ini
extension=xml.so
extension=gd.so
extension=ctype.so
extension=simplexml.so
extension=session.so
extension=bz2.so
extension=curl.so
extension=mbstring.so
extension=zlib.so
extension=mysql.so
;extension=libmcrypt.so
;extension=mcrypt.so


What are the requirements for this script?
Thank you in advance

I just swiched back to previous working version 200903??.

PageRank test is working
Mass Add also works perfect (in actual version 20090603 mass adding large number fo urls /in my case 100 lines/ is
almost imposibile - every link is added slower than previous.)


Thanks
Tomek
