After updating Marketpress:
Lightbox for featured image:
I use another plugin for the lightbox. The result was that I had two light boxes.
Nice but a little overdone.
I disabled in /wp-content/plugins/marketpress/marketpress-includes/template-functions.php on line 1915
$class = ' class="mp_product_image_link mp_lightbox"';
//$class = ' class="mp_product_image_link mp_lightbox"';
After that it is working great.
Languages files (mo and po)
I also lost my additional languages files for Italian and English.
Not a big deal, I had a backup, only a little bit more work.
Is there a way to prevent this when you are updating to a newer version
