Known issues that affect installation

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

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:
