Fixing WordPress Plugin Conflicts: A Buffalo Developer Guide
By Artur Bobinski ·

When your WordPress site breaks after an update, a plugin conflict is usually the culprit. Learn how to diagnose these issues like a pro and restore your site's functionality.
Managing Your WordPress Site in Western New York
Hi, I'm Artur. I have been running Kenton Web Design since 2003, and over the last 23+ years, I have handled more than 300 client projects here in Lockport and the greater Buffalo area. One of the most common calls I get from business owners in Western New York involves a website that was working fine one minute and completely broken the next. Most of the time, the culprit is a WordPress plugin conflict.
Signs You Have a Plugin Conflict
Identifying a conflict early can save you a lot of stress. Usually, you will notice something is wrong immediately after you click 'Update' in your dashboard. However, some conflicts are subtle and might only affect specific pages or features.
Look out for these common red flags:
- The website displays a blank white page (White Screen of Death).
- Certain features, like your contact form or image gallery, stop working.
- The layout of your site looks garbled or the navigation menu disappears.
- You receive an email from WordPress stating your site is experiencing a technical error.
- The administrative dashboard becomes extremely slow or inaccessible.
The Step-by-Step Troubleshooting Process
Before you do anything, make sure you have a full backup of your website. If you are on one of my Care Plans, this is already handled for you, but if you are DIYing it, don't skip this step. The most reliable way to find a conflict is the process of elimination.
First, you should switch to a default WordPress theme, like Twenty Twenty-Four. If the problem goes away, the issue is likely with your theme code. If the problem persists, it is definitely a plugin. Next, go to your plugins page and deactivate everything. Check your site—it should look plain, but the error should be gone. Now, reactivate your plugins one by one, checking your site after each activation. The moment the error returns, you have found the offending plugin.
Finding a Permanent Fix
Once you identify the problematic plugin, you have a few options. First, check if there is an update available that might have fixed the bug. If you are already on the latest version, you can try reaching out to the plugin developer's support forum. Often, they are already aware of the issue and have a patch ready.
In some cases, the conflict happens because your site is running an outdated version of PHP or your WordPress core is behind. Keeping everything updated is the best defense against these issues. If the plugin is essential and there is no fix, you might need to find an alternative plugin that offers the same functionality without the code errors.
Improving Performance After a Conflict
Sometimes, fixing a conflict reveals that your site has become bloated and slow over time. Heavy plugins don't just cause conflicts; they drag down your page load speeds, which hurts your SEO and frustrates your customers in Buffalo and beyond. Once your site is stable, it is a great time to look at optimization.
I offer a flat-fee WordPress speed optimization service for $795. This is a deep dive where I clean up the database, optimize images, and ensure your site loads as fast as possible, usually completed in 5-7 days. A fast site is less likely to run into resource conflicts that lead to crashes.
Professional Support for Your Business
I know that as a business owner in Western New York, you probably don't have the time to spend hours deactivating plugins and checking error logs. That is why I offer Care Plans to take that weight off your shoulders. My Essentials plan starts at $149/mo and includes one hour of hands-on help. For businesses that need more active management, the Growth plan is $399/mo with three hours, and the Priority plan is $799/mo with five hours.
These plans ensure your site stays updated and secure. If a conflict does happen during a routine update, I am there to fix it immediately so your customers never see the error. Please note that unused hours in these plans do not roll over to the next month.
Frequently asked questions
Why did my WordPress site break after an update?
Updates often introduce new code that may be incompatible with your current theme or other active plugins. This is known as a plugin conflict.
Can I fix a plugin conflict without losing my data?
Yes. Deactivating plugins does not delete your data or settings. Once you resolve the conflict and reactivate the plugin, your data will still be there.
What should I do if I get the White Screen of Death?
The fastest way to recover is to rename your plugins folder via FTP to deactivate all plugins, then reactivate them one by one to find the culprit.
