Yes it fixes again, then after a couple of days it happens again. it goes like that.

i am using lots of plugins, i thought it can be wp super cache plugin. i disabled the wp super cache plugin and waiting that if it will be happened again. unfortunately it did not occur quickly. it has been 3 days, it is working now.

thanks.
