If you are receiving error mentioned above after installing typo3, please follow the steps below.
1. Open the file typo3_src/t3lib/config_default.php
2. Find for ‘no_pconnect’ the default value set will be 0. Change the value for ‘no_pconnect’ to 1. This will look like
‘no_pconnect’ => 1
3. Save the file and exit.
mysql_pconnect will be disabled on servers for security reasons. By default, typo3 uses mysql_pconnect to connect to the database. Changing the value for no_pconnect to 1 will use mysql_connect to connect to the database.
