Pleks Panel - Syntax Error Problem

Pleks Panel - Syntax Error Problem

Error that we handled:
  syntax error, unexpected end of file in /var/www/vhosts/username/httpdocs/index.php on line 248

This error occurs because of short_open_tag option in PHP settings. If you are sure your code is clear and does not include syntax error, you should open short_open_tag option. This feature is closed by default.

SQL - Attitudes types to adopted record when referenced record is deleted

  1. CASCADE: This enables us to remove its all adopted records when parent is deleted. For example, we have removed blog record, its adopted comment records will be deleted.

  2. RESTRICT: This enables us to prevent deletion of record when it has a adopted record at least.

  3. These enable us to set data that we want into relation column of adopted records that we will remove its parent.

  • SET NULL:
  • SET DEFAULT:
  • SET (...):
  1. NO ACTION: It does not anything. You should avoid choose this inside all of these choices.
