I'm almost sure it's something small, I don't see. But in the mean time I'm almost desperate because it doesn't work. Tomorrow the site has to go online for a client.
So, I cannot give a public link yet because it's not online, not finished yet
I use NextGen Gallery as base.
Short info + code I added to Alt/description field following the instruction on the 'official' page.
I added this code, coming from the settings: [wp_cart:Timeless:price:39.50:end]
I also tried this one, found somewhere else [wp_cart:Timeless:price:39.50:END]
I typed it in manual, I copied and pasted and whatever I do no button shows up. No cart image either, while I controlled the link several times.
Then I added the shortcode [nggallery id=12 template=wp-eStore] to a page.
Everything shows up as it should except the cart image. It just shows the complete text of the code and not a nice cart as it should, I suppose.
I also went to the host, to synchronize ht.access because I thought maybe that could cause the problem. But.... nothing helped.
I don't know anymore how to solve this.
