I don’t think I can do that without allowing access to the admin panel.

No. I’m writing them directly into the control panel.
Even if I make no changes and continue to click on the update post button all words with an apostrophe will add the quotation marks each repost.

Latest version yes.
I’m using the Colourful Bird theme but the problem exists even if I use the default theme.

I have no plugins installed.

Thank you for that esmi. Centering worked.
