If it’s a plugin issue then you’ll simply have to rename or delete the plugin folder found in /wp-content/plugins/
Log into your web host and look for the File Manager module, or use an FTP program to gain access to the actual files.
In the public_html, or root folder you’ll see the following three folders along with the WordPress core files:
wp-content
wp-admin
wp-includes
Browse into wp-content > plugins and simply rename the jetpack folder to something obscure like “jetpackold” and then try logging in again.
If you’re able to login then either JetPack conflicted with the theme or with another plugin and caused the error. Upgrading to the latest WordPress or making a note of how other plugins interact with Jetpack will help you to solve the issue if you still want to use Jetpack.
Keep us posted!

Thanks for the advice – that was perfect. I used WinSCP to FTP into my site and started to remove Plugins. It looks like it was the better-wp-security/better-wp-security.php plugin that was the culprit. I deleted the folder out of the plugins directory and now I can access the site.
Thank you thank you!
