Strangely, I can no longer update my About page. I haven’t tried to update it since months and I’ve upgraded my wordpress to the latest version one not long ago. It’s only now that I realise that I cannot edit my About page any more. After I press Save, the page is redirected to post.php instead.
My other pages can be edited successfully. That’s so strange. I had to edit my About page via the database instead but still, it’s really troublesome to have to do that each time I want to edit my About page.

I have edited my About page via the database and deleted all the text and saved the page. Then , I went in my wordpress ‘Manage pages’ page to edit the About page. I wrote the word ‘testing’ and pressed Save. The page could be edited successfully. It seems that it’s a word in my About page which was causing my page not to save properly.
I had kept a copy of my About page content so I pasted one paragraph of text and pressed the Save button. I did this for the rest of the paragraphs until the page doesn’t save and gets redirected to post.php instead. Then I pasted sentences by sentences until I managed to track down the word which was causing all this trouble.

It’s the word ’s e t’ . (sorry for the spaces in between, my post won’t save otherwise. )
I then edited my Links page (just to see if I get the same problem with other pages)and put the word ’s e t’ at the very beginning and the page can still be saved.
I put the word one paragraph below and it could still be saved. When I write that word further down or at the end of the page, the page cannot be saved. So weird.
