Is there, refresh, please. Thank you,
I recommend asking at https://wordpress.org/plugins/azindex/#new-post so the plugin’s / theme’s developers and support community can help you with this.
HOWEVER, that plugin hasn’t been updated for NINE YEARS!
I urgently suggest you find a different plugin.
Also, the # is in the title of each post. Is that what you see when you edit one?
I know, it is on each post. On its title. How would I got about editing all of them at once and remove them?
Thanks,
You might try the plugin “better search replace”. Search for # (or however many blanks follow the # and replace with nothing, in the wp_posts table.
This may break things, so be sure to backup your database first. Note: Starting post tiles with numbers may lead to other conflicts, so try a couple of changes manually (edit one by one) first.
