I have a problem with one of the plugins and I guess that this forum is not offering support for plugins so, this is why I am asking for wp support and I think that the problem might be from wordpress
Here is the problem :
I have the plugin called "Wordpress Premium Content" from jigowatt. I have bought the plugin and I have posted this problem like 2 weeks ago. But no answer to my ticket. The plugin can make an standard article into a premium.
In the "Premium Content" box, when I try to switch from NO to YES (see image http://tutorial-z.com/uploads/error.jpg ), after I click the Update or Publish button, it wont stay on Yes, but it will switch back to NO.
First, I have thought that it might be a problem on the plugin, but until now it worked, so ... i guess that its nothing wrong with the plugin.
I have disabled all other plugins, and nothing, the problem persists. I have installed the plugin on another website and it worked. So, I guess that it might be because of wordpress ( I am using the 3.5.2 version)
Here is my ON Topic question :
I would like to know how can I reinstall the wordpress without loosing any content (comments, pages, articles, etc). I have found an answer here : http://wordpress.org/support/topic/reinstall-wordpress-without-losing-the-contents-of-the-site
But since I am not very efficient at this kind of stuffs, can you please tell me "How to..." in a step-by-step way ? And I would also like to know how to make a backup for wordpress and for the database
Thank you :)
