Here i going share with you a good website that i use to check the IP reputation. The website called mxtoolbox. (more…)

Recently i found a problem on my Thunderbird lighting calendar. The reminder keep on pop up and i can’t even dismiss any reminders at all.

So, i just go thought my Thunderbird calendar. I realize that my calender properties setting was tick the Read-only setting.

So, to fix this issue, i just un-tick the Read Only check box on my calendar properties. After that, i try to dismiss the calendar again. It work fine and the reminder not pop up again.

  • Select Tools | Options… or Edit | Preferences… from the menu.
  • Go to the Composition category.
