I have installed a new theme designed by me (PakPoint Theme) at my site http://www.pakpoint.com . This is working fine. But at random occasions my site changes to the default them. I have to logon as an admin and then restore my them. Any one can suggest what is wrong?
I am not sure what was the problem, may be some plug in have caused this. So I was unable to figure out which plugin. I have solved the problem just by replacing the name of my theme with the default one. Now the name of my current theme is default so the problem is solved.
