If there was some error during the installation/update of CyberSEO Pro and your site just crashes every time you are trying to open it, you should recover the code. Here is the instruction.
- Delete the
cyberseo.pro
file from the/wp-content/plugins/cyberseo/
directory of your website. - Download the recovery script from here.
- Extract the
recover-cseo.php
file and upload it to the root folder of your website (the same folder wherewp-config.php
is located). - Open the script in the browser. E.g.
https://mysite.com/recover-cseo.php
where mysite.com must be replaced with the actual domain name. - You should see the following message: “Recovering CyberSEO Pro…Done.”
- Upload the
cyberseo.pro
file back to the/wp-content/plugins/cyberseo/
directory of your website. - Important: Remove
recover-cseo.php
from your server. - Go to your WordPress control panel and reactivate CyberSEO Pro.
You can also use this procedure, except points #1 and #6, to reset your registration info for CyberSEO Pro versions prior 10.000.
