Reminds me a lot of YOOTheme’s Cloud template. Definitely needs more uniqueness.
FYI, I’m currently experiencing this issue right now for one of the themes I purchased (456theme).
There are 2 versions of that theme. A WordPress version and an HTML/CSS version. Be sure you are commenting on the correct one. I noticed you posted a WordPress related comment on the non WordPress version.
Facebook pages have changed a lot since I use to admin them over a year ago (pre timeline era), but if it’s anything like it use to be…
Facebook templates are just websites that you host on your own webspace that have a set width and height dimension to them. Then, as a facebook page administrator, you can create an iframe tab for your facebook page and set that template as the url for the iframe. This allows your facebook page viewers the ability to see your website, without leaving facebook.
Here is an example. borderlands game
I don’t know anything about opencart or its database table structure, but there is a php code requesting a mysql query that just doesn’t exist in the database according to that error. I looked on google, and that table, product_tags is a table from an old version of the software that is no longer used. http://forum.opencart.com/viewtopic.php?t=82463
I would direct your theme buyers to that link and inform them that they need to fully upgrade their opencart software for the error to go away. To be safe, they should obviously run a database backup beforehand. Just incase anything goes terribly wrong with that update script.
Hope that helps in some way.
For a project I have been working on lately, I found USA ePay to be the best choice. They accept basically all forms of digital payment (including echeck which was important for me) and they take only a small percentage of the payment. Their api has been really nice too.
I also considered amazon’s fps and Stripe.com, but amazon was pricier and Stripe didn’t have all the features I needed.
