I am facing a strange problem here.
I am getting a page not found error on many page of my website. but not regularly, the problem fades away once when i save the permalinks settings. but after a few minutes it again shows up the error. so far I have checked my .htaccess file which is exactly the same as wordpress supports. I have contacted my hosting support and they are saying all seems to be OK from their side. I have lot of plugins installed so it is quite tough for me to check disabling all one by one. more ever I cannot catch the exact plugin conflict if there is any, as even now the problem remains for some time and gone in next.
here is a link. please test all links here. and as I said it may run properly. but if you try it again and again I hope you may get the problem.
please help guys.
