Thread:Project:Support desk/Unexpected non-MediaWiki exception encountered, of type "Exception" /extensions/yambe/yambe.php:553/reply (5)

I tried to reproduce your problem by using the wikitext you provided and the yambeUnpackTag function and couldn't get the problem. And then I realized you didn't give us a PHP version.

In any case could you edit the Yambe extension where it says:

$xml = new SimpleXMLElement($xmlstr); so that I says: error_log("XML: $xmlstr"); $xml = new SimpleXMLElement($xmlstr);

and then reproduce the error. After that, could you look at your error log and see what error it printed out?

If you don't have access to the error log, then something like the following should  work on the page that usually displays the error: var_dump($xmlstr); exit; $xml = new SimpleXMLElement($xmlstr); Of course, after you've done that, you'll want to remove it.
