I installed Kloxo again.
It is problem with 5.3.29, 5.4.45 works good, but i need 5.3, becouse it is an old forum that generates many errors.
Also I tried php_5.3.3 and it gives the same as 5.3.29 result with 500 error, that doesn't find classes. If I don't do anything in kloxo cp panel site goes right, but at 6 o'clock in the morning it goes wrong . Probably kloxo does some background work, and i have to restart php-fpm.
Is there any solution to make php5.3 to work?
