I've posted to trac about this as well but I have just pulled 3.1 which by the looks of it will have 3.1 beta 2 merged in it. I now have a serious failure due, I believe, to my php version which is 5.3.3, the Centos standard release.
[Warning] DOMDocument::saveHTML() expects exactly 0 parameters, 1 given
Line 529 of ShortcodeParser.php :
529: foreach($html->childNodes as $child) $res .= $doc->saveHTML($child);
Research suggests that this does not work less than php 5.3.6. See [url]http://www.php.net/manual/en/domdocument.savehtml.php[/url] You may wish to revisit version requirements or alter code as
Many users such as me cannot easily go beyond 5.3.3 so this is an issue.
It has been pointed out by DirtyHam that 3.1.0 beta 2 works with 5.3.3.
A quick glance shows that 3.1 and 3.1 beta are quite different in this file. The offending php method is still present in 3.1 but not the beta.
The functions loadHTML() and saveHTML() are added in 3.1. There's a few other differences too. The offender is saveHTML(). The will not work sub php 5.3.6.
Assuming this is acceptable and deliberate then it should be added that to requirements. I am at present building a copy of my main centos server so I can add the remi repository to it and test upgrading php to (up to) 5.4.x.
