Drupal adds modules to the inexplicable error of the solution (often appear in the module more time) _php skills

The status is as follows:
1, click the Security button, can not go to the normal page, a blank page appears;
2, refresh the page, issued a number of navigation items have not been, but also the existence of the item can not be clicked into the normal page.
Tested a number of times did not find any problems, many times reload, test, finally appeared a error page hint: "Drupal Maximum execution time seconds exceeded database In/mysqli.inc", A look at this document, finally found a light of dawn. Baidu, found that there are three solutions, and try to solve the problem.
These methods are now noted:
Method One: Change the php php.ini file, set the Max_execution_time value to a larger point.
Method two: Change with PHP code, call the Ini_set () function to set, such as Ini_set (' Max_execution_time ', 1000), The call to this function can be added to Drupal's settings.php, but the best call to this function is canceled after the operation is complete.
Method Three: (never tried) find the My.ini (my.cnf) file in the root directory of MySQL and find the last line when you open it
[Mysqld]
port=3306
Add the following:
Set-variable = max_allowed_packet= Set a larger number, such as 10M
