Bad value for attribute “href” on element “a”: Illegal character in query: space is not allowed. [SOLVED]
If you have received the following W3C validation error then this will help you solve the issue.
Line 290: Bad value for attribute “href” on element “a”: Illegal character in query: space is not allowed.
onclick=”javascript:window.open(this.href, ”, ‘menubar=no,toolbar=no,resizable=yes,scrollbars=yes,height=600,width=600’);return false;”>
Remove the 2 spaces in the code:
this.href, ”, ‘menubar=no,toolbar
The code should now read:
this.href,”,’menubar=no,toolbar
The issue will now be resolved.
