Error 330 (net::ERR_CONTENT_DECODING_FAILED): Unraveling the Compression Issue

Upon encountering the enigmatic "Error 330 (net::ERR_CONTENT_DECODING_FAILED)" while navigating to a dashboard page, it's essential to delve into the root cause. This error typically arises when a web server misidentifies the content compression method used in an HTTP request.

Compression Configuration Complications

OpenX, the adserver in question, relies on PHP settings for optimal operation. A deviation from the recommended configurations can lead to compression-related issues. Specifically, if the server misjudges the content as being gzip-encoded when it's not, the decoding process fails, resulting in the frustrating error.

Pinpointing Potential Culprits

The following factors can contribute to the compression error:

• Incorrect HTTP headers: If the request headers incorrectly indicate gzip compression when it's absent, the server will attempt to decode non-compressed content, leading to failure.
• Server side misconfiguration: The server may be incorrectly configured to apply gzip compression to certain content, even when the content is not actually compressed.

Troubleshooting Tactics

To resolve the issue, consider the following steps:

• Consult server logs: Inspect the error logs of the web server and application server to identify any related error messages or warnings.
• Review server configuration: Verify the PHP settings as outlined by OpenX. Ensure that "zlib.output_compression" is disabled, and "mod_deflate" is not active in Apache.
• Disable compression temporarily: Turn off compression either in the application or server configuration to determine if the issue persists.
• Contact hosting provider: If all else fails, reach out to your hosting provider for assistance in further debugging the server compression settings.

By meticulously following these troubleshooting measures, you can resolve the "Error 330 (net::ERR_CONTENT_DECODING_FAILED)" and restore the smooth operation of your OpenX adserver.
