Greetings,
I'm working on a locally installed XWiki, using the 0.9.840 release. I've got a couple problems with Wiki syntax that I need assistance with.

First, I want to use the {pre} tags around some text, but XWiki seems to be stripping the tags out. For example:

  this {pre}*text*{/pre} sample

...will show up with "text" in bold type. When I edit the page, the {pre} tags are gone.

  this *text* sample

Our XWiki installation is very new. {pre} worked for a while, but then stopped working, making me question whether there was a (system?) change made a some point that caused {pre} to stop working.

I've also got problems where Wiki {table} will turn to HTML the next time the page is edited. Is this related to, or somehow a clue to the {pre} problem?

Thanks in advance for any assistance,
John
