How To Fix 508 Error Codes On WordPress

How To Fix 508 Error Codes On WordPress

An HTTP error 508 code is encountered when your WordPress site account has been requesting resources that exceed its allocation. For every website hosted on a shared remote server, a particular proportion of resources such as memory, processing time, and power is allocated. 

Now, the size and magnitude of this server resource allocation could vary depending upon the available space and server resources and the plan that you have chosen for your hosting account. 

So, when you get an error code saying ‘508- resource limit is reached’, it means that you have exceeded the allocated resource, and the server is hence not able to serve your requests. So technically, the error is not exactly an error but a warning or notice for you to figure out the underlying cause and fix it. 

Read on to find the most common causes for the 508 error and how to fix it. 

508 Error Code Description

A 508 error code is usually accompanied by the error message ‘ Resource limit reached’ or ‘Loop detected.’  The former could be raised due to resource limitations, while the latter could indicate a recursive logic that makes the server loop on a particular operation. 

How To Fix 508 Error

Fixing the website error codes is similar to fixing 502 bad gateway error. You find the root cause and find a solution to deal with it. Here are some of the common causes and their respective solutions. 

Browser Cache

When the browser cache memory is corrupted, it can sometimes lead to looping requests that overload the server and cause a 508 error. 


Perform a hard reload of the web pages with the Ctrl+shift+R key combination. This will override any cache. You can also empty and clear out your entire browser cache to fix the issue. 

Caching Plugins

Some plugins you use in your WordPress site might have a faulty or corrupted cache that leads to a 508 error. Such errors are commonly observed with CDN or any caching plugin like WPRocket on WordPress. 


Login as site admin into your WordPress account. Enter the settings for the caching plugins, clear the cache, delete files, and regenerate the CSS. 

In case you use Cloudfare CDN, login to your account, Go to the Settings page and find the Cache Purge option. Clicking on this option will clear out the cache and outdated files. 

Recursive Links

Faulty plugin code logic or redirect setup can cause a request loop that causes recursive redirects and, subsequently, a 508 error. In many cases, faulty plugins can also lead to 404 error.


You can try uninstalling any redirection plugin you use and use the latest version of it. Or you can find alternatives that work well. You also need to check whether you have set up the redirection links properly. 

If none of the above fixes seem to work, you can directly alter the .htaccess file to check for any recursive redirects. Go through every link, especially the relative links. 

Resource Limit Reached

In most cases, a resource limit reached error message indicates a simple problem. Your site has exceeded the allocated resource usage within your shared just environment. Resource limits can exceed due to various reasons like increasing web traffic, unoptimized code, huge file sizes, and growing data query sizes, and so on. 


The first thing you need to check is your cPanel hosting account. Find all the stats related to your account and see which script or process is eating up your resources. You can try to identify the particular process, node, or logic that causes a spike in resource usage and try to optimize it. 

If an increase in web traffic is what is cashing the resource spikes, you may need to optimize your entire website for better performance or move to a better plan that allows for increased resource allocation.

DDoS Attack

Your server could run out of resources when you are under a denial of service attack. These attacks flood your server with multiple requests, simultaneously making it impossible for the server to serve legitimate requests. It can be done via special scripts or botnets, which are a collection of interlinked computer systems designed by hackers to launch a DDoS attack. 


Secure your website with proper security measures like captcha for logins and proper authentication to avoid bots from accessing your site. Remove unwanted forms, registrations, and any such user-specific submissions and web requests that can be exploited by hackers. You can get inspired by the security measures adopted by

Once you are under a DDoS attack, it may take a while for you to figure out the exact cause for your server downtime. You need to check up with your hosting service provider and identify the IP addresses from which the attack is launched. Once identified, block any request from those IP addresses. This should help your site to get back online 


Sometimes hackers could install malware on to your server, which might place an additional load on server resources, making it difficult for the server to operate on legitimated web requests. 


Run a malware scan on your server regularly and fix any issues if found immediately. Adopt strong security measures and install security plugins and firewalls to prevent any further attack. You can contact your hosting partner to make sure the server is free from malware. 

Website Performance

When your website has outdated coding and inefficient resource handling, it may lead to resource spikes. 


Make sure your website is always operating at optimal performance. Remove unused and resource-heavy scripts and use optimized plugins and code in their place. Avoid querying for large amounts of data and, instead, find ways to filter and carry out database operations in an efficient way. 

Make sure to use only the necessary plugins and update them regularly. Remove all unused themes and plugins.

The Wrap Up

So, this is how to fix resource limit is reached error. As you can see, all it needs it a bit of trial and error to understand the root cause. Follow the basic troubleshooting steps that we mentioned above, and you should be good to go.
