Until this licensing server tie-in is removed, this product has a lot of risks for production servers. I know this author is fearful his software is going to be compromised but, putting legitimate customers site at risk of not working is a poor business decision. I would look at another solution if this is unacceptable to you.
I will have to start looking for another solution again and that's too bad since this plugin integrates so well with CB and has some good modules. Another upside to this product is the uploader, which is first class! I will also check on refunds.
What led me to figure this out is my customers site started getting the dreaded IE7 Cannot open site XXX errors. When I went into the component in the admin, I thought it was a corrupted key.php error so I deleted the key.php from the server as the instructions on the site says to do.
"Everytime you update your license key, or update your domain/IP, you may have to delete the key.php file to continue. key.php located in /components/com_simgallery/"
This is what I did and not I get the error:
SIMGallery License Error: Unable to communicate with iono (i.e. http://www.ionolicensing.com/). I verified this by digging into the server logs.
As of this writing, the authors server is still offline and so is my customers gallery.
This happened because my host was under ddos attack and was down for 16 hours. This is also the first time and only time such an unfortunate incident happened, and I am currently looking at other hosting options.
Do note that the license checking process is done only once every 10 days, so there is actually little chance of it occurring.
I am disappointed that you hadn't tried to contact me directly, instead of opting to write in a review for a problem that wasn't my fault. In any case, such incidents are pretty rare, and the host has already looked into the matter.
