Unable to add new post/page

Hi there,

i replied directly to your email - to cover here where we can keep the conversation open:

The Theme isn't responsible for publishing posts - thats a core WordPress function.
First thing to try is to rebuild your permalinks.

Go to Dashboard > Settings > Permalinks and click the Save Changes button.

Then retry publishing your post or page.

Try to understand.
Look this site: https://bikedirector.com/
I am unable to update the homepage. When I edit text and update then I get this error: I am unable to add new post,page. when I click publich then i get this error: OOPS! THAT PAGE CAN’T BE FOUND.
It looks like nothing was found at this location. Maybe try searching?

Two things to check/try:

1. In Settings > Reading make sure your Home page is set to Static and the correct page is selected.
2. Try rebuilding the permalinks as i stated above.

Hi, I know everything.
My main problem is you dont understand my problem
Have you checked my homepage?
If yes, Then look:
i want to edit my home page text. so i edited text and when I click update then I get this message:
OOPS! THAT PAGE CAN’T BE FOUND.
It looks like nothing was found at this location. Maybe try searching?

again understood,
The homepage is unable to edit/update .. when i want to edit and click update then I get the error. other pages/posts are working fine..

Can you provide temporary admin login to your site so i can see whats happening.
You can share those details on the Private Information field.

You're using the Classic Editor plugin - the site requires you to use the Block Editor

Yes. Now working. Thanks

Glad to hear that
