Error: DNS application 'LogExporter.App' class path was not found: Log Exporter

I'm getting this error in the app and can't seem to get it to work otherwise. Any assistance would be great.

Did you install the “Query Logs (SQLite)” plugin under Apps in Technitium?

I have it and Query Logs (PostgreSQL) installed as well as the Log Exporter app. Does this create a conflict?

Sorry, I’m a little late with my reply. I was on vacation and had a lot going on. But now I’ve finally had some time.

This combination likely exposes a bug in the extension's automatic log-app detection.

Technitium distinguishes between apps that receive/export query logs and apps that provide queryable stored logs. The Log Exporter is a logging/export app, but it is not a valid source for the /api/logs/query endpoint.

Since you have Query Logs (SQLite), Query Logs (PostgreSQL), and Log Exporter installed, the extension is probably selecting the wrong app — LogExporter.App.

As a temporary test, please do the following:

1. Disable the Log Exporter app.
2. Leave only one query-log backend enabled, either Query Logs (SQLite) or Query Logs (PostgreSQL).
3. Open the extension Service Worker console and run:

chrome.storage.local.remove(["queryLoggerApp"]);

4. Reload the extension, try again and report back if you can.

I’ll provide a fix for this in the next update (after next weekend). The extension will distinguish between export-only apps and queryable log providers, avoid selecting Log Exporter, and correctly choose either the SQLite or PostgreSQL query-log backend. If multiple valid providers are installed, I’ll also make the selection deterministic instead of relying on whichever app is returned first.
