There was a post about this but I couldn't reply cause the conversation was closed. We are just starting to work with wordpress and I was testing out different templates. I went to test out one so I clicked activate and tried to view my page and there was the white screen. I wasn't able to log into my wordpress admin area or anything. We have had this happen three times now and only thing we have been able to do to get wordpress account back is to reload wordpress but in doing this all our information pages, discussion board etc are gone. Our page seems to be set back to maybe a "default" page? I am wondering whath happens once we are in full use of this and blogging away and "bam" everything gets lost again. In the other posts I have seen people had to update some function.php but I am not sure where that is or even if that will help alleviate the problem.
I am just really worried all our info will be lost once we start to blog and really dive into wordpress. I currently have the page back up but hesitant about spending time on it and the white screen appearing again.
Is there a back up that you can do with wordpress in case this happens again so that all your information and posts are not deleted?
