 +=== Possible problems after installation. ===
  
 +
 +**1) I performed a platform action and suddenly a blank page is displayed**
 +
 +A PHP error has being triggered.  Find the actual error in system error log. Look for strings of type  "''Fatal error:''"
 +
 +The most possible reason is that some php module hasn't been installed or php version is too old. In most cases a php module installation / upgrade is required.
 +If fatal error still exists contact us.
 +
 +**2) In various pages the following message is being displayed**
 +
 +"''In file /home/eclass/public_html/include/lib/hierarchy.class.php on line 1031 : Unable to execute statement:"Column count of mysql.proc is wrong. Expected 20, found 16. The table is probably corrupted", sqlstate:"1547", errornum:"HY000", statement:"SHOW PROCEDURE STATUS WHERE Db = ? AND Name = 'add_node'", elapsed:0.00073000000000001"''
 +
 +
 +
 +This is due to upgrade from mysql version 5.0 to version 5.1. In mysql version 5.1 the structure of table proc has been changed.
 +
 +From terminal enter the following command:
 +"''mysql_upgrade --force -u root -p [your mysql root password]"''
 +
 +mysql will be upgraded correctly. After that, continue with the platform upgrade.
