Correlates WordPress PHP errors, slow queries, hook data, and external dependencies to surface the most probable root cause — not just individual symptoms.
The most time-consuming part of WordPress debugging is not finding individual errors — it's connecting them. A PHP notice in the log, a slow database query, an external API that's timing out, and a hook with an unusual priority can all be symptoms of a single underlying cause. Root Cause Analysis automatically cross-references data from all active WordPress diagnostic collectors and surfaces correlated findings — so you spend less time connecting dots and more time fixing the actual problem.
The RCA engine reads findings from the Error Log Aggregator, Request Profiler, Hook Inspector, External Dependency Monitor, and DB Health module simultaneously and identifies patterns that span multiple WordPress data sources.
Every WordPress finding is assigned both a severity (Critical, Performance, or Informational) and a confidence rating (High, Medium, or Low) based on how many independent data sources corroborate it. A high-confidence critical finding means multiple modules agree on the same probable cause.
Each correlated finding includes a plain-language explanation of the probable root cause, the evidence collected from each module, and a specific recommended action — targeted guidance based on your WordPress site's actual data.
For each WordPress finding, the module shows exactly which data points from which modules contributed to the correlation — so you can verify the reasoning and drill down into any module for more detail.
Where the correlated evidence points to a specific WordPress plugin or theme as the likely source, the finding is attributed directly — so you can go straight to the responsible code.
Individual modules show WordPress data in isolation. RCA finds relationships between that data. A slow database query, a hook that fires immediately before it, a plugin updated yesterday, and a PHP warning referencing the same class — individually just observations; together they point to a cause.
RCA reads from any module that has collected data in the current session: Error Log Aggregation, Request Profiler, Hook Inspector (via Blast Radius), External Dependency Monitor, DB Health Inspector, and Conflict Detector.
Yes — correlation is not causation, and the confidence rating reflects this. A Low confidence finding means the data is suggestive but not conclusive. Always verify findings before acting on them on a live production WordPress site.
No. Root Cause Analysis is Pro-exclusive and requires data from at least two other active WordPress diagnostic modules to produce meaningful findings.
Cross-references all your WordPress diagnostic data automatically — so you can stop guessing and start fixing.
Root Cause Analysis is included in every Pro plan alongside all seventeen diagnostic modules.
