Sitecore 8: Sending reminder mails without knowing

Environment: Sitecore 8.o rev 150621

When I setup new instance on one of our production environment, I have experienced the following message on Sitecore log files.

ManagedPoolThread #14 11:24:06 INFO Executing email reminder task
ManagedPoolThread #14 11:24:06 INFO Parameters: <r><to>name@company.com</to><txt>Demo reminder</txt></r>
ManagedPoolThread #14 11:24:06 INFO Sending reminder mail (to: 'name@company.com', from: 'name@server.net', subject: 'Reminder from Sitecore')
ManagedPoolThread #14 11:24:06 INFO Using mail server: 'smtp.company.com'

When this message logged to the Sitecore logs it says there are some unwanted reminder mails are sent to the Sitecore content authors. 
The reminder emails sending are not expected by the content authors and they are usually outdated.

We have raised a Sitecore support ticket and their suggestion is to manually change the values which responsible for this in the database.

To change the values within the Sitecore database: 

1. Login to your website SQL Server.
2. Go to the website's Sitecore core database.
3. Select * From Tasks
4. Check the resulting table's 'Pending' column.
5. Check if there are any 1 's (Which means reminders are sending)
6. Change required values to '0' using the bellow query.
    Update [Tasks] Set Pending = 0; (This will make all the values to 0, so use whatever the where clauses you want and run the query.)

Sitecore 8 - System.ArgumentException: Directory does not exist. Parameter name: directoryVirtualPath

Environment: Sitecore 8 rev. 150621

When I work one of our projects. I have experienced the following error:

Directory does not exist.
Parameter name: directoryVirtualPath

NOTE: Get the latest Sitecore databases from your CI or Release environment which already installed the required Sitecore modules.

The error message describes there is a required directory (folder) missing in your solution.

If you have copied the Sitecore correctly this can be due to not coping a required Sitecore module.

Go to the config files of your solution to figure out what are the Sitecore modules that used in your solution.

Since the solution is not working and you can't access the Sitecore desktop to install modules, extract required module and copy the files and folders inside \package\files and paste to your website root.

Since your database has the required items of the Sitecore modules, copying the files of the module is just enough. 

This should do the work.
