Xoops 2.0 Error In Php I cant get my pages to load.

Hi, I've recently installed XOOPS 2.0 on one of my subdomains, http://forums.xisto.com/no_longer_exists/ and after I'd posted a new entry today, it started showing up a blank index.

 

I got into my admin area and turned on PHP debugging mode and this is the error message I get:

 

Parse error: parse error, unexpected ')' in public_html/sims2/html/modules/wordpress/wp-content/plugins/markdown.php(774) : regexp code on line 1

 

Fatal error: Failed evaluating code: ''.str_repeat(' ', - strlen('') % ) in public_html/sims2/html/modules/wordpress/wp-content/plugins/markdown.php on line 774

I've no idea what that means. I've posted news topics on the site before and nothing like this has happened.

 

I've turned my site off temporarily. Could someone please tell me what the above errors mean (in simple terms, if you can?) thank you sooooooooooo very much in advance!

A PHP File in your script is either corrupt or has been edited, I recommend that you reinstall XOOPS

Okay, thanks.I've already uninstalled it. I was unable to back up my data before I did that Will be looking around at other CMSes, any good ones to recommend?
