Hello, I just installed a new wiki and for some reason I cannot save page edits. I can preview, but as soon as I press 'save page' it gives me a "Fatal exception of type MWException" error. I tried to switch on error display but the errors themselves are cut off the top of the page. Here's what I managed to save:
- Warning: preg_match(): Compilation failed: assertion expected after (?( at offset 115 in /home/linweb07/a/anglofur.co.uk-1071752405/user/htdocs/swordtail/includes/IP.php on line 124
- Warning: preg_match(): Compilation failed: assertion expected after (?( at offset 115 in /home/linweb07/a/anglofur.co.uk-1071752405/user/htdocs/swordtail/includes/IP.php on line 112

I am getting errors like that on every page of the wiki, but only saving edits to pages seems to be affected. Previously I had problems with Extensions but I thought I had resolved them.
