Hi,
1- I can't say anything about PHP5.4 Never attempted to test our template, because it doesn't necessary.
take a look at here:
dev.virtuemart.net/projects/1/wiki
It says; requirements: PHP 5.2 and PHP5.3
If Virtuemart isn't supported by PHP5.4 (or generates some error message) then you can't expect our templates to work with PHP5.4 as well.
You should better wait for Virtuemart2.1 before upgrading to PHP5.4 lots of things will change with VM2.1 (it will support Joomla3.0)
2- I don't know about that "content-encoding-error" issue.
Did you recently changed your Firefox configuration settings? I am not receiving that kind of error, and no one has ever reported this before.
Check this page:
support.mozilla.org/en-US/questions/945251
And try to do what they suggest.
3- About not willing to index the quicklook page by google. It is a relatively easy thing to do.
Open this PHP file:
/templates/flexible_lightmart/html/com_virtuemart/category/default.php
and search this keyword:
&flexiblelayout=quicklook where ever you see a link that includes that keywords, include this attribute:
rel="nofollow"
for example, find this line:
<a class="FlexibleProductHoverShadowQUICK" title="<?php echo $product->product_name; ?>" rel="facebox" rev="iframe|550|900" href="<?PHP echo JRoute::_ ( 'index.php?option=com_virtuemart&view=productdetails&virtuemart_product_id=' . $product->virtuemart_product_id . '&tmpl=component&flexiblelayout=quicklook&virtuemart_category_id=' . $product->virtuemart_category_id);?>"><?php echo JText::_("TPL_FLEXIBLE_QUICK_LOOK"); ?></a>
replace it with this:
<a rel="nofollow" class="FlexibleProductHoverShadowQUICK" title="<?php echo $product->product_name; ?>" rel="facebox" rev="iframe|550|900" href="<?PHP echo JRoute::_ ( 'index.php?option=com_virtuemart&view=productdetails&virtuemart_product_id=' . $product->virtuemart_product_id . '&tmpl=component&flexiblelayout=quicklook&virtuemart_category_id=' . $product->virtuemart_category_id);?>"><?php echo JText::_("TPL_FLEXIBLE_QUICK_LOOK"); ?></a>
