It is really sad that JSKit which was running a good commenting system said good bye to webmasters and left them in lurch and went for greener pastures. Now the only option available for the subscribers of JSkit was to shift to Disqus for retaining their old comments and have a good commenting system. Worst of all Jskit had promised that all comments will be syncrionised with Blogger which never happened despite numerous correspondence with them on the subject. They always stated that it has been syncronised though in actuality it never happened on the ground.
One can download the comments file from JSkit data base by clicking on Sites I manage as shown in screenshot below.
A XML file is generated which can be saved and same can be transported to Disqus migration tool by using link http://import.disqus(dot)com/ (remove dot from link and replace with actual). However agony does not end because if you have more comments than you are likely to get an error as stated below:
It is a grave problem and on digging with Disqus they sent a response as stated below:
To resolve this, we’d recommend running your import through W3C’s XML validator found here: http://validator.w3(dot)org/#validate_by_upload and making the necessary corrections before re-importing. (remove dot from link and replace with actual)
Thanks for using Disqus,
Keep on loading the file every time as somewhere I read after 4th or 5th time you may succeed. Do not run 2 uoploads simultaneously.
As a last resort request JSKIT to send you your file as we requested them and they obliged and we found that the file size which we downloaded through their online system had a different size than which was sent to us by their officials.
We have worked on Plan C and have again uploaded in Disqus and hope for best as it is taking 30 hours for result to come out i.e. whether it is uploaded or not. The problem is with big files and as a last resort you can break the file into small bits with a help of a web designer who knows how to break up xml file and upload small files which upload easily. Alternatively use the services of online sites which perform tasks from $5 to $25 like freelancer or elance etc and they will be happy to help you out.
