Topic on Extension talk:Widgets

hi,when I ran the widgets, I always get this error:"unknown modifier "validate"".Anyone can help? thank you

Which one?

thanks for the reply. All the widgets go wrong. Here is the error detail:

【Syntax error in template "wiki:wiki:PDF" on line 1 "<object class="pdf-widget" data="" type="application/pdf" wmode="transparent" style="z-index: 999; height: 100%; min-height: px; width: 100%; max-width: px;"><param name="wmode" value="transparent">" unknown modifier "validate"】

To me this looks like the extension was not installed and set up correctly. If think I saw this issue somewhere before but cannot remember where it was. Perhaps someone else can make more of it.
