Re: TikiWiki 2.0: Odd Tags get Inserted into HTML Code eg style tag
This is the unintended side-effect of a procedure that is done to prevent malicious insertion of code. It isn't random — particular vulnerable strings are broken up but the break isn't meant to make it to final page output and the method is still being refined (which is why RC releases). Have you upgraded to revision 14085? Using the latest SVN will actually be the answer AFAIK. I was experiencing the same thing but after upgrading I don't see this problem in wiki pages anymore.
