I really loved this plugin it was easy and convenient. However after installation if you try to validate your XHTML at validator.w3.org I received 23 Errors and 23 warning(s).

I uploaded the patch and it works! This is a very useful mod that adds a fully functional SEO manager into the Joomla 1.5.6 Core. The only issue I have is an error when I revalidated my XHTML.

Potential Issues

The following missing or conflicting information caused the validator to perform guesswork prior to validation. If the guess or fallback is incorrect, it may make validation results entirely incoherent. It is highly recommended to check these potential issues, and, if necessary, fix them and re-validate the document.

1. Warning No Character Encoding Found! Falling back to UTF-8. None of the standards sources gave any information on the character encoding labeling for this document. Without encoding information it is impossible to reliably validate the document. As a fallback solution, the "UTF-8" encoding was used to read the content and attempt to perform the validation, but this is likely to fail for all non-trivial documents.

My XHTML was validating without errors before I copied the patch now it is NOT marked as XHTML 1.0 Transitional

Just what I was looking for, now I can keep control of my Joomla 1.5 feeds. Great looking Icons. So easy to install.

mtwMigrator worked just as stated. It was so easy using this extension. The only issue I had problems with my 500 server error timeouts due to my large content data file. My work around was to migrate the jos_content file separately then it worked. If you have large menu files or content files I would suggest migrating them one at a time after the initial migration.
