Sound familiar?

These are the symptoms. SmartFix finds the cause.

A site breaks after an update

Plugin or theme update introduces a conflict that wasn't there before.

Checkout stops working

Two plugins hooking the same WooCommerce action interfere with each other.

Forms stop submitting

Conflicting JavaScript or duplicate libraries prevent form handlers from firing.

CSS or JS loads twice

Multiple plugins enqueue their own copy of jQuery, Bootstrap, or Select2.

Duplicate meta or SEO output

Two plugins both inject meta tags, Open Graph data, or schema markup.

Something conflicts but you can't tell what

The symptoms are subtle and the cause is buried across 20+ active plugins.

Detection Engine

13 conflict types. Three analysis passes.

Rule-based detection, AI pattern analysis, and a database of known bad plugin combinations — running in parallel.

Critical

Hook priority collisions

Broken execution order

Two plugins hooking the same action or filter at the same priority. WordPress executes them in undefined order.

High

Duplicate asset detection

Performance & JS errors

Multiple plugins enqueue their own copies of jQuery, Bootstrap, Font Awesome, or Select2.

Critical

Post type & REST collisions

Data loss risk

Two plugins register the same custom post type slug or REST API endpoint.

Critical

WooCommerce conflicts

Broken checkout & payments

Duplicate payment gateways, checkout field collisions, cart hook conflicts.

Varies

AI pattern analysis

Subtle interaction bugs

AI model detects non-obvious conflicts: shortcode stripping, filter chain interference, resource competition.

Varies

Known conflict intelligence

Pre-verified issues

Database of known bad plugin combinations verified across thousands of sites.

Critical

Vulnerability correlation

Security exposure

Cross-references conflicts against CVE data. A conflict involving a vulnerable plugin gets flagged with elevated priority.

High

Performance & cron analysis

Slow scheduled jobs

WP-Cron collisions, database query conflicts, and memory limit prediction across active plugins.

Varies

Environment drift detection

Staging-vs-prod surprises

Compare two sites: PHP version, extensions, MySQL, memory limits, plugin versions. Find why staging works but production breaks.

Common questions

Is SmartFix safe to run on production?

Yes. Scanning is completely read-only. The Auto-Fix Engine uses standard WordPress APIs, is always reversible, and never edits plugin files.

What data does SmartFix collect?

Plugin names, versions, hook registrations, and asset handles. No user data, no post content, no credentials, no PHP source code.

Do I need an account to use the free plan?

No. Install from WordPress.org, activate, and scan. No account, no API key, no email.

What is the Auto-Fix Engine?

A Pro feature that applies runtime compatibility shims to resolve common conflicts. Fixes are deterministic, reversible, and never edit plugin files. Critical hooks are always blocked.

Can I check a plugin before installing it?

Yes. Pre-Install Compatibility Scan downloads the plugin from WordPress.org, analyzes its code, and checks for conflicts against your existing plugins. Free gets 1/month, Pro gets unlimited.

Your next plugin update might break something.
