  • Hi,

  • Hello,

    Try either disabling the zlib output compression or you can also try replacing the core files of WP. (If you have access to cPanel and if server runs on EasyApache 4 then this can be done via multiPHP Manager)

    Steps to replace core files manually :

    1. First take the website files backup before making any changes.
    2. Download the wordpress zip file from https://wordpress.org/download/
    3. Upload the zip file to domain directory. If it is a primary domain then it would be public_html or www
    4. Extract the zip file which you have uploaded
    5. It will unzip the files in a folder called wordpress.
    6. Go to wordpress folder and delete the folder wp-contents (you are deleting the folder which you have uploaded not of your website)
    7. Move all the files from wordpress folder to website directory.
    8. Try creating page/post now

    Hope this helps…

    Hello,

    In this case shouldn’t be the same to REINSTALL WordPress from the Update page in the backend?

    Yes, you can try that. Make sure that before making changes it is good to take the backups and proceed with the re-install.

    Agree with @amrut4858 advise +1

    Check to see if you have php.ini file and if it states

    zlib.output_compression = On

    Change it to

    zlib.output_compression = Off
