Why Stripe Plugin Conflicts with Other Plugins

WordPress websiteMultiple plug-ins installed in your system that load JS scripts, CSS files, or PHP functions with the same name may cause a resource conflict that can affect the normal operation of Stripe Checkout or Payment Intents.

1.2 Plug-in functionality overlap

Some security plugins, caching plugins modify form submissions, rewrite JS requests, and cause Stripe to not properly communicate with the server.

1.3 jQuery and Dependency Library Version Conflicts

Second, how to quickly troubleshoot Stripe payment failure causes

2.1 Acknowledgement of error messages

First, check the Stripe Dashboard for error alerts for failed transactions, common errors include:

• Invalid API Key provided
• Payment Intents failed

2.2 Switch to Default Theme Test

Switch the current theme to the WordPress default theme and test the payment again. If the payment function is restored, it means the theme has JS or PHP code that is incompatible with the Stripe plugin.

2.3 Disable plugin-by-plugin troubleshooting

Disable all plugins except Stripe and WooCommerce in the WordPress backend and test if payment functionality is restored. If it comes back, re-enable the plugins one by one and test to find out which plugin is causing the conflict

2.4 Checking Cache and Security Plugin Settings

If a caching plugin is enabled (e.g. LiteSpeed Cache) or security plug-ins (e.g. Wordfence, Sucuri Security), are required:

• Exclude Stripe-related checkout pages, API callback URLs
• Ensure that firewalls are not blocking Stripe Webhook requesting

2.5 Checking SSL and HTTPS Configuration

Keep Stripe, WooCommerce, themes and other plugins up to date to avoid conflicts due to version compatibility issues.

3.2 Using the Official Stripe Plugin

Prioritize the use of official Stripe plugins (WooCommerce Stripe Payment Gateway), avoid using payment plug-ins from unknown sources.

3.3 Setting Exclusion Rules in the Cache Plugin

Make the following settings for the cache plug-in:

• Exclude Stripe checkout page
• Excluding Stripe Webhook URLs
• Disable JS/CSS merging and delayed loading of Stripe related files

3.4 Avoid enabling multiple optimization plug-ins at the same time
