Hi,
The error you are seeing is related to a file (seoanalyzer.php) that does not exist or is not used in Route 66 version 2.x. This usually happens if the installation is incomplete or if PHP’s opcache is still caching old files.
Since you have tried multiple times with the same result, I recommend the following steps for a clean upgrade:
PREFIX_route66) and delete them manually if found.Please be aware that following this process will delete all your previous settings, SEO scores, and sitemaps.
If you want us to help perform this upgrade safely, please create a private ticket and provide administrator credentials and FTP access so we can assist you directly.
Let me know if you need further assistance!
Best Regards,

Hi Luigi,
Have you had a chance to follow the steps I recommended in my previous reply?
Please ensure you follow them exactly as described and make a clean install of version 2.0.4. If the issue persists, kindly open a private ticket and provide administrator credentials along with FTP access so we can investigate and assist you directly.
Best regards,
Lefteris
It’s great that you’re testing in a staging environment.
Please note that since the last two releases of Route 66, we haven’t received any reports of upgrade issues. Upgrading your production sites, which are still running the v1.x series, should be smooth and trouble-free — and if not, we’re here to help.
Best Regards,
Lefteris
