[Plugin: Recently Updated Pages] Page won´t update

Im having a problem – I haven added new plugins recently and made some changes… which is why this problem is very odd.
I tried updateing a page on my webpage, I entered the new info and clicked on “Publish” nothing happened, the new info I entered disappeared and the page was not updated.
Can you help me?
