OnlyMonster Browser Troubleshooting Guide

If the OnlyMonster Browser won't run (an error is displayed, or the application does not open), follow these steps to troubleshoot

OnlyMonster Browser won't run

1. Reboot Your Computer

Rebooting your computer periodically helps applications run faster and more smoothly. If the browser doesn’t launch, reboot your PC and try again.

2. Check Your Operating System

OnlyMonster Browser is optimized for Windows 10 and macOS 11.0 or later. If you're using an older version, please update your operating system to the required version.

3. Check for Antivirus or Firewall Interference

Antivirus or firewall software may block the browser for the following reasons:

— Blocking executable files: Some antivirus programs mistakenly flag the browser as unsafe and block it.

To resolve this:

— Disable your antivirus and firewalls: Temporarily turn off your antivirus and firewall to check if they’re causing the issue. For Windows users, ensure that Windows Defender Antivirus and Windows Firewall are also disabled. Follow these steps:

How to Disable Windows Defender Antivirus:

• Open the Start Menu and search for Windows Security.

• Click on Virus & Threat Protection.

• Under Virus & Threat Protection Settings, click Manage Settings.

• Toggle off Real-time protection to temporarily disable Windows Defender.

How to Disable Windows Firewall:

• Open the Start Menu and search for Windows Defender Firewall.

• Click on Turn Windows Defender Firewall on or off in the left panel.

• Select Turn off Windows Defender Firewall for both Private and Public network settings.

After disabling the antivirus and firewall, try launching OnlyMonster Browser again.
