Greek portal dictionary not working anymore

Whatever changed, it's better to try and make the wikitext more robust. Have you tried seeing what is the output of Special:ExpandTemplates for that page?

Thanks for the tip. I found out that it does no longer accept the syntax:

{|
<tr><td>test</td></tr>
|}

result:

test

Do you know why is that? Is it because of some new policy I am not aware of or could it be just some new bug?

I am asking this so as to know whether to change it to pure wikitext or not.

Update:

It seems it was way more easier to change it to pure html instead. Now it works fine again!!!

But my question still stands if someone knows the answer.
