How to Resolve HTTP Error 508 WordPress Sites

Mar 10, 2022  |  

Error codes on a WordPress website are a pain to deal with. And, unlike some other errors, HTTP error 508 WordPress is a little more difficult to diagnose. Not because the error is particularly bothersome, but because two 508 errors loops have been detected and a resource limit has been surpassed. Two 508 errors loops have been discovered, and the resource limit has been reached. The first is an HTTP error, which occurs when a loop is discovered in either a resource or URL request, and the second occurs when the server is overburdened and unable to fulfill the operations. In any case, we'll walk you through these problem codes so you can get your site back up and running as soon as possible.

What Is HTTP Error 508 WordPress: Loop Detected, and What Does It Mean?

A link or resource is called from somewhere on the website, which then calls another resource, which then calls the original resource. The server never gets to complete the request since the reasoning is recursive and loops back on itself.

The HTTP error 508 is actually quite uncommon. In terms of loop errors, you're more likely to encounter a "too many redirects" error, which occurs when someone has mishandled 301 and 302 redirects to the point where the server never gets to complete the request since the reasoning is recursive and loops back on itself.

How to Fix HTTP Error 508 WordPress?

It's a relatively simple fix in general. If you see this problem, we recommend bypassing the cache by reloading the page with CTRL/CMD – Shift – R and then clearing your own browser cache to ensure things aren't hanging up on your end.

If you're a server administrator, there are a few options available to you. If you're using a CDN or cache plugin on WordPress, the first step is rather straightforward

If you're using WP Rocket, simply go into the settings and look for the options to clear the cache, erase files, and/or regenerate CSS.

If you have a Cloudflare or other CDN service, you'll be able to access the Cache Purge option in the settings.

If neither of these options resolves the redirect issue and your resources continue to loop recursively, you should look into your.htaccess file. URL redirections are stored here (unless you use a 301 Redirect plugin). An FTP client and a code editor are required. Alternatively, you can use the web-based file manager on your site.

Examine each link you've included, especially if you've used relative links. Check to see if any of them are recursive. It's actually quite simple, especially if you're dealing with a lot of redirects. The same can be said for your plugin. Make sure you verify all of the URLs in the plugin settings to make sure they're all the same.

If none of this works and the resources continue to loop, you should contact your host. From their end, they should be able to assist in closing the loop.

What is the HTTP Error 508 WordPress: Resource Limit Reached?

The resource limit reached notice is the other 508 issue that users and administrators have to deal with (and it's probably the most common). This one is also quite self-explanatory. Your website has used up all of the server's available resources. This can happen for a variety of reasons, but the first place to go is your cPanel (if you have one) or your dashboard if you don't.

There will be a full set of stats about your server somewhere on your page. Databases, server executions, inodes, and other information will be displayed. The full statistics will show you which scripts and processes were run within which timeframes.

If you see a surge in these, or if your inodes or space are filling up, it's a good indication that something is wrong. It's possible that you'll need to think things out a little.

You’ve Been Subjected to a Distributed Denial-Of-Service (DDoS) Attack

If you are under a DDoS attack, your server may run out of resources and report an HTTP error 508 WordPress. A distributed denial of service (DDoS) attack occurs when someone floods your website with so much traffic that it can't handle it. Typically, this is accomplished through the use of a botnet, which is a huge network of linked computers controlled by a single person or a group of people.

If your server is DDoSed and crashes, there isn't much you can do right away. You might not even be aware that you've been subjected to a DDoS attack. You've just realized that your server is down. Check with your host to discover if there have been any unusually significant traffic spikes.

If that's the case, you may block the attack's IP ranges, and your server should be back up and running in no time.

You Obtain a Significant Amount of Traffic

You can also return a 508 if your server becomes overburdened and is unable to accept legitimate requests. Perhaps you received a lot of traffic from Reddit or from a particularly well-written Tweet. Contact your host and increase your plan if your server is offline for this and returning an HTTP error 508 WordPress. That's all there is to it. You want your servers to be up and operating as soon as possible.

Malware

Remember those botnets we talked about earlier? Your server, for example, could be a part of one and you're not even aware of it. If you don't know about malware on your server, it could be diverting resources that should be flowing to your website to something else. So do a virus scan, install a good WAF and security plugin (Sucuri, WordFence), and make sure your server is doing its job: assisting your website in its success. Not crashing into other people's computers.

Additionally, if your site is functioning slower than usual and nothing has changed, you should consider scanning it for malware. That's usually a sign that it's about to run out of resources.

CRON Jobs, Unknown Scripts, and Unused or Outdated Plugins

You should also be mindful of the overall performance of your website. Make sure you do site checks on a regular basis and that you use the different debug and error logs that you have access to, whether through your web host or directly on your site. These will show you any running CRON jobs as well as any scripts that may be running in the background at various periods. In many circumstances, none of them are required.

Final Thoughts

Many folks will never encounter an HTTP error 508 WordPress in the end. The primary technique to avoid seeing it is to use redirects efficiently and avoid recursive loops in your request and back-end code. And if your resources are being misused, your CPU is being strained, and your site is experiencing downtime, there are a few simple tests you can run to identify the cause of the problem and take immediate action.
