Unable to load page URL on my WordPress website

  • Unknown's avatar

    Hi

    On my WordPress website, I’m trying to open my existing pages but it’s showing me “It seems we can’t find…”.

    This problem occurs when I update WordPress to new version every time. Newly added pages works fine but old one’s are showing “It seems we can’t find…”.

    When I update their URLs, then they start working properly.

    Can you please tell me what’s the main problem.

    Before updating URL:

  • It seems we can't find...
  • After updating URL:

  • It seems we can't find...
  • Here is website
