When you click on the Facebook app on your phone or computer, only to find that it won't open properly, crashes, or gets stuck on the loading screen, it can be incredibly frustrating. This is especially true when you're about to post important content, reply to client messages, or manage multiple ad accounts.
There are various reasons why Facebook might not open: it could be an app cache issue, system version incompatibility, server downtime, or even that your account has triggered the platform's risk control mechanisms. For marketers, e-commerce sellers, or social media management teams who need to manage multiple Facebook accounts simultaneously, such problems not only affect work efficiency but can also lead to account bans or business interruptions.
This article will provide comprehensive solutions and practical steps from the perspectives of individual users and multi-account managers to help you quickly restore Facebook to normal use and reduce the risk of encountering similar issues in the future.
Before we dive into troubleshooting, let's understand some common reasons:
1. Accumulated App Cache or Outdated Version
The Facebook app generates a large amount of cache data during usage. When this data accumulates to a certain point, it can cause the app to run slowly, lag, or even fail to launch. Additionally, if you haven't updated the app for a long time, the old version might be incompatible with your system or the server.
2. Facebook Server Downtime
Even tech giants like Meta occasionally experience server outages. With hundreds of millions of users worldwide, any server issue can lead to widespread app malfunctions or inaccessibility.
3. Device or Network Issues
Insufficient phone memory, an outdated operating system, or an unstable network connection can all affect Facebook's normal operation.
4. Account Triggered Risk Control or Ban
For multi-account operators, frequently switching accounts on the same device or IP address, logging in from different locations, or using automation tools for bulk operations can easily be detected by Facebook as "suspicious activity," leading to account restrictions or even inability to log in.
The simplest solutions are often the most effective. When the Facebook app won't open or crashes, try force closing it and then restarting it:
This method can clear the app's temporary runtime state and resolve most crashing issues caused by memory usage or process conflicts.
If the problem persists after restarting the app, it's likely a Facebook server issue. You can quickly check this by:
If the page shows a large number of users reporting Facebook as inaccessible, it indicates a server-side problem, not an issue with your device. In this case, you'll need to patiently wait for the official fix, which usually occurs within a few hours.
If the first two steps don't resolve the issue, it's probable that the app's cache or data has become corrupted. You'll need to thoroughly clear and reinstall the app:
iPhone Users:
Android Users:
This process will force an update of Facebook to the latest version and clear any cache files or corrupted data that might be causing the crash.
If you need to manage multiple Facebook accounts simultaneously—such as operating several brand pages, ad accounts, or providing social media services for different clients—you'll face higher risks of account bans and login obstacles beyond the common issues mentioned above.
Facebook's risk control system monitors the following suspicious activities:
Once risk control is triggered, you might encounter:
Let's use a typical scenario to demonstrate how to manage 3 Facebook ad accounts using MasLogin:
You are a cross-border e-commerce practitioner who needs to manage 3 Facebook ad accounts for different brands simultaneously:
Operational Steps:
1. Download and Install MasLogin

Repeat the above steps to create separate environments for the UK and Japanese markets, ensuring each environment uses the corresponding regional proxy IP and language settings.
3. Log in to Facebook Accounts within Isolated Environments

Perform the same operations for the other two accounts, ensuring each Facebook account runs in its own isolated browser environment.
4. Team Collaboration and Permission Management (Optional)

If you have team members managing these accounts together, you can use MasLogin's "Share Environment" feature:
5. Daily Maintenance Recommendations
Individual Users
If you only occasionally need to manage 2-3 Facebook accounts, you can prioritize trying these methods:
However, if you need to operate multiple accounts stably in the long term, or if the accounts hold significant value (e.g., linked to substantial ad budgets), it is recommended to use professional tools like MasLogin to fundamentally isolate account environments.
Team Users
For social media management teams, ad agencies, or cross-border e-commerce companies that require multi-person collaboration, MasLogin's advantages are even more pronounced:
Clearing the cache can only resolve issues with the app itself. If the problem lies with the server or network connection, you need to check if Facebook is down or try switching network environments (e.g., from Wi-Fi to mobile data).
No. MasLogin simply creates isolated browser environments and does not interfere with Facebook's normal functions. You can post content, run ads, reply to messages, and perform other actions just as you would in a regular browser.
Not necessarily. Facebook allows users to have multiple accounts (e.g., personal and business accounts), provided these accounts have distinct purposes and are not used for fraudulent activities, spamming, or other violations. Using MasLogin can reduce the risk of accidental bans due to technical associations, but you must still adhere to Facebook's Community Standards and advertising policies.
A VPN can only change your IP address; it cannot isolate critical information like browser fingerprints and cookies. If you use a VPN to switch accounts within the same browser, Facebook can still identify these accounts as belonging to the same operator through device fingerprinting.
Facebook not opening might seem like a minor glitch, but for users who rely on social media for their business, any disruption can lead to losses. With the 3-step quick fix methods introduced in this article, you can quickly restore normal app usage. For multi-account managers, leveraging professional solutions like MasLogin not only helps avoid ban risks caused by technical associations but also significantly enhances team collaboration efficiency and account security.
