 * Hi Maeve,
 * I have a few questions before buying the pro version :
 * – how does it work if the free version is already in place : do all settings 
   just reset (is it better to save the css files first for instance) ?
 * – is the pro version valid according to w3c markup ? (I corrected 2 errors in
   the free version, see below)
 * => wpc-catalogue.php, line 151 : $return_string .= ‘ “/></div>’;
    you need to
   delete the quote mark => wpc-catalogue.php, line 157 : $return_string .= ‘<br
   clear=”all” />’; better to transform it into $return_string .= ‘<br style=”clear:
   both;” />’;
 * Thanks a lot for your answers !
 * Regards,

 * If you have been using the free version of the plugin you need to deactivate 
   it first, then install and activate the Pro version. You will not lose any data
   if you do it this way. Once Pro version is active, then you can delete the free
   version via FTP. DO NOT DELETE free version via your WP Plugins dash because 
   that will also delete the data. If you have never used Free version then just
   install and activate this plugin as normal.
 * On CSS changes, if you did them in your theme (which is where you should have
   done them) then you’re fine. Updating the plugin will not overwrite and pro version
   uses mostly the same styling except for responsive adjustments). If you made 
   css changes in the plugin css then updating free would overwrite them and upgrading
   to pro would bypass the.
 * Does that help?
 * As for code validation, this is a plugin with lots of different types of code(
   mostly php) so you can’t run the whole thing through a validator. W3c doesn’t
   validate php, it can only validate the html sections by running it through the
   xhtml parser. …I think you are asking me if the code is perfect? ;-p Well I tried
   my hardest but I offer no guarantee that I am faultless. If you identify a bug
   please report it and I will be very happy!
 * Thanks
    Maeve
