Simple SEO URL (OLD version) [support thread]

[askaquestion]

Hi, thanks for writing an excellent add on. I've just installed the mod and it works fine. However, I also have installed the login box add on. I'm trying to get 100% valid html across my site (and I'm almost there). When the login box add on is switched on (and Simple SEO isn't) the html is valid. If both are on the html becomes invalid. If the login box is off then the html is also valid. So, I'm not sure what's happening.
Here is the error report from W3's Validator. I think its just the & not being read as "&".
Help would be very much appreciated.

# Warning Line 435, Column 185: cannot generate system identifier for general entity "zenid".

An entity reference was found in the document, but there is no reference by that name defined. Often this is caused by misspelling the reference name, unencoded ampersands, or by leaving off the trailing semicolon (;). The most common cause of this error is unencoded ampersands in URLs as described by the WDG in "Ampersands in URLs".

Entity references start with an ampersand (&) and end with a semicolon (;). If you want to use a literal ampersand in your document you must encode it as "&" (even inside URLs!). Be careful to end entity references with a semicolon or your entity reference may get interpreted in connection with the following text. Also keep in mind that named entity references are case-sensitive; &Aelig; and æ are different characters.

If this error appears in some markup generated by PHP's session handling code, this article has explanations and solutions to your problem.

Note that in most documents, errors related to entity references will trigger up to 5 separate messages from the Validator. Usually these will all disappear when the original problem is fixed.

This is usually a cascading error caused by a an undefined entity reference or use of an unencoded ampersand (&) in an URL or body text. See the previous message for further details.

If you meant to include an entity that starts with "&", then you should terminate it with ";". Another reason for this error message is that you inadvertently created an entity by failing to escape an "&" character just before this text.

This is generally the sign of an ampersand that was not properly escaped for inclusion in an attribute, in a href for example. You will need to escape all instances of '&' into '&'.
