    <p>Just confirming that the issue exits: I get about the same traceback, the site itself looks fine, but for every click inside the site I get a the following traceback in my instance fg:</p> <pre><code>2012-08-10 15:05:05 ERROR plone.transformchain Unexpected error whilst trying to apply transform chain Traceback (most recent call last): File "/opt/etc/buildout/eggs/plone.transformchain-1.0.2-py2.6.egg/plone/transformchain/transformer.py", line 48, in __call__ newResult = handler.transformIterable(result, encoding) File "/opt/etc/buildout/eggs/plone.app.theming-1.0-py2.6.egg/plone/app/theming/transform.py", line 257, in transformIterable params[name] = quote_param(expression(expressionContext)) File "/opt/etc/buildout/eggs/Zope2-2.13.10-py2.6.egg/Products/PageTemplates/ZRPythonExpr.py", line 48, in __call__ return eval(self._code, vars, {}) File "PythonExpr", line 1, in &lt;expression&gt; AttributeError: 'FilesystemResourceDirectory' object has no attribute 'Language' </code></pre> <p>This is because I have the following line in my manifest.cfg (which is about the same as the parameter line in the plone_control_panel:</p> <pre><code>lang = python: context.Language() </code></pre> <p>In a way in my case this is sort of logical, since not all content objects have an index called Language().</p> <p>But the 'context' in this case is apparently refering to the 'FileSystemResourceDirectory' and not to the piece of content you are on? I'll try with pdb if I can find some more info...</p>

    1. COIt might be possible to do the same thing (check if there are portlets on the left) with a diazo rule instead of a parameter, like check for the existence of portal-column-one?: ... if-content="//*[@id='portal-column-one']"

    2. COright, at the end I also used the css-if condition... but the 'parameter expressions' could be very useful in other user-cases

    3. COCan you try and work out which url exactly is causing the problem? Use the Chrome or Firebug net panel to see the list of requests then visit each individually until you find the offending url. I think I've seens something like this before where a TinyMCE resource made this happen. It needed the X-Theme-Disabled header adding to prevent plone.app.theming from attempting to theme the page.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
