Wordpress - Fatal error: Maximum execution time of 30 seconds exceeded



I am downloading plugins etc in wordpress and getting the following error


Fatal error: Maximum execution time of 30 seconds exceeded in .................


Solved it by changing the value for the param max_execution_time in php.ini, like this:


  • max_execution_time = 360      ; Maximum execution time of each script, in seconds (I CHANGED THIS VALUE)
  • max_input_time = 120          ; Maximum amount of time each script may spend parsing request data
  • ;max_input_nesting_level = 64 ; Maximum input variable nesting level
  • memory_limit = 128M           ; Maximum amount of memory a script may consume (128MB by default)

The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine.

The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine.


Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.InvalidOperationException: The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine.


SOLUTION / FIX : 

the 64-bit framework dlls weren’t able to 32-bit versions of the 'Microsoft.ACE.OLEDB.12.0' provider modules.

If you are running Visual Studio on a 64-bit machine, IIS 7 is not (by default) serving 32-bit applications.

However, the database engine operated on 32-bit.

Follow these steps to fix the issue:

1.    Open the IIS 7.5 manager and select the application pool corresponding to your web application.
2.    Right click the application pool and select ‘Advanced settings’.
3.    Select the field ‘Enable 32-bit applications’ and change it to 'true'.
4.    Restart your application pool and access your application to fix the error you saw.

No mapping exists from object type System.Web.UI.WebControls.

I am getting the the message on the command:

commandObj.ExecuteNonQuery();

Complete message is:

No mapping exists from object type System.Web.UI.WebControls.TextBox to
a known managed provider native type.



Solution: its actually a very silly mistake 

Seems as if  you set the DataBinding on the TextBox/Label itself instead of the Text property of the TextBox/Label?

for Example: 

cmdInsert.Parameters.Add(new SqlParameter("@LastName", txtLastName));

Instead of
cmdInsert.Parameters.Add(new SqlParameter("@LastName", txtLastName.Text));
