If you use the optional PHP extension xdebug, you can encounter exceptions:

• During installation
• Accessing either the Magento Admin or storefront after a successful installation

Sample exception:

Fatal error: Maximum function nesting level of '100' reached, aborting!

To resolve this issue, you can:

• Disable the xdebug extension.
• Set the value of xdebug.max_nesting_level to a value of 200 or more. For more information, see xdebug documentation.

After you change the configuration of or disable xdebug, restart Apache:

• CentOS: sudo service httpd restart
• Ubuntu: sudo service apache2 restart
