For ages I've been reading the advice on the forum on how to remove the Ask A Question button from the product detail page as the tick box option in the admin section did not remove it. The solutions posted didn't quite work for me, I don't know if it was me not following instructions correctly or not understanding things. I'm using Joomla 2.5.7. and Virtuemart 2.0.10.
Anyway, I have now managed to do it so I thought that I would detail it in simple steps how I did it.
1. Accessed the deault.php file through my ftp client following this path- /web/templates/vmshopblue/html/com_virtuemart/productdetails/
2. Accessed the default.php file
3. Edited and removed lines 109 - 112 in Dreamweaver -
<div class="ask-a-question">
<a class="ask-a-question" href="<?php echo $url ?>" ><?php echo JText::_('COM_VIRTUEMART_PRODUCT_ENQUIRY_LBL') ?></a>
<!--<a class="ask-a-question modal" rel="{handler: 'iframe', size: {x: 700, y: 550}}" href="<?php echo $url ?>"><?php echo JText::_('COM_VIRTUEMART_PRODUCT_ENQUIRY_LBL') ?></a>-->
</div>
4. Saved file and uploaded it to the server.
5. Refreshed the site and the Ask A Question button was gone!!
I hope that this works for you if you've been having difficulity in removing the button. :)
For me the selector "Show the Ask a question link? " in Config/Shopfront works just fine, but if making the edit described above be sure to save the edited file as a template override to prevent it getting overwritten during future VM updates.
