Thread:Project:Support desk/"-----" causing errors in wikipedia

Whenever an article has "" in the text I get

'''403 Forbidden

You don't have permission to access /wiki/index.php on this server.'''

Error when editing or previewing. This suddenly started. How do I get rid of this problem and could be the cause?
