Fix WordPress Intermediate Errors on CyberPanel Like a Pro

If your WordPress website, hosted on CyberPanel or CloudPanel, displays intermittent errors or goes down unexpectedly, you have come to the right place.

Several factors, such as server misconfigurations, resource limitations, or problematic WordPress plugins, can cause these issues.

Today, we will look at a step-by-step process to diagnose and resolve these errors.

Troubleshooting Tips

Step 1: Check the Server Logs

To begin with, let’s head to the server logs. These logs can offer vital clues about what’s happening behind the scenes during downtime or when errors occur.

The logs are in different locations as per the OS template:

• For CyberPanel:
  • Apache or LiteSpeed Logs
    • Error log: `/usr/local/lsws/logs/error.log`
    • Access log: `/usr/local/lsws/logs/access.log`
    • Stderr log (LiteSpeed): `/usr/local/lsws/logs/stderr.log`
  • CyberPanel Logs
    • General logs: `/usr/local/CyberCP/logs`
• For CloudPanel:
  • Nginx Logs (default web server)
    • Error log: `/var/log/nginx/error.log`
    • Access log: `/var/log/nginx/access.log`
  • CloudPanel Logs
    • General logs: `/var/log/cloudpanel`
    • Site-specific logs: `/home/cloudpanel/var/log/`

Server logs are often the first place to start your investigation for more specific CyberPanel issues, such as “This site can’t be reached” errors.

Step 2: Monitor Resource Usage

Sometimes, CPU or memory usage spikes can lead to intermittent site errors. We can use tools like htop or top in the terminal to get real-time system metrics.

If we are using Hostinger VPS, review the usage graphs in the dashboard. Look for recurring spikes that align with cron jobs, backups, or high-traffic periods.

If you’re using CyberPanel, clearing the cache can also help reduce resource usage. Here’s a quick guide on how to clear the cache in CyberPanel.

Step 3: Analyze Access Logs

A sudden surge in web traffic could indicate malicious bot activity or a DDoS attack. We need to review the access logs to identify unusual patterns in this case.

We can resolve this issue by implementing a Content Delivery Network (CDN) like Cloudflare to block suspicious traffic and reduce server load. It also improves performance and security.

Step 4: Review Cron Jobs

Furthermore, misconfigured or resource-heavy cron jobs can destabilize the site. So, make sure all cron jobs are running as expected.

We can use plugins like WP-Cron Control to manage better and schedule WordPress cron tasks.

Step 5: Inspect WordPress Core, Plugins, and Themes

Sometimes, the WordPress configuration might be at the heart of the issue.

So, disable all plugins and switch to a default theme to rule out compatibility problems.

Additionally, enable debugging in the `wp-config.php` file:

define('WP_DEBUG', true);

define('WP_DEBUG_LOG', true);

define('WP_DEBUG_DISPLAY', false);

Here are some useful debugging plugins:

• Query Monitor: Inspects database queries, hooks, and PHP errors.
• Debug Bar: Displays debug information in your WordPress admin area.

Site errors can sometimes result from failed uploads or login issues. For more targeted fixes, check out our solutions for CyberPanel login errors and upload-related problems.

Step 6: Check MySQL Performance

Database bottlenecks can also lead to intermittent errors. We can use the MySQLTuner script to audit and optimize the database server in this scenario.

Run these commands:

wget https://raw.githubusercontent.com/major/MySQLTuner-perl/master/mysqltuner.pl

chmod +x mysqltuner.pl

./mysqltuner.pl

The tool will provide optimization tips. We can follow these suggestions to boost database performance.

Step 7: Apply Fixes and Optimizations

After identifying the root cause, you can consider one of these options:

• Upgrade server resources if we are consistently hitting memory or CPU limits.
• Caching plugins (like WP Super Cache or W3 Total Cache) can be used to reduce server load.
• Optimize the database with tools or plugins like WP-Optimize.
• Fine-tune the server configuration based on traffic needs.
• Deploy a CDN to improve performance and reduce load during traffic spikes.
