I am trying to lessen the errors shown by W3C validation on my backup-copy of the html homepage. I know I cannot remove all of them.
I have a UBB 7.1.1 forum.
I post news from the forum on my homepage by linking to specific forum threads.
I get these warnings and errors on W3c validation:
Warning Line 129 column 86: cannot generate system identifier for general entity "Number".
...om/forum/ubbthreads.php?ubb=showflat&Number=163506">
Error Line 129 column 86: general entity "Number" not defined and no default entity.
...om/forum/ubbthreads.php?ubb=showflat&Number=163506">
Error Line 129 column 92: reference to entity "Number" for which no system identifier could be generated.
...um/ubbthreads.php?ubb=showflat&Number=163506">
How can I correct these?
Thanks.
