Hello. Thank you for contacting the Toolset support.
I just checked with the latest Types plugin version 3.3.8 with PHP 7.4 and I can see the button to register the Toolset plugins.
Can you please make sure the Types plugin is installed correctly. Maybe you should consider reinstalling Types plugins again and check if that helps you to resolve your issue.
If that does not help, please feel free to send me admin access details and I would be happy to troubleshoot the issue further.
*** Please make a FULL BACKUP of your database and website.***
I would also eventually need to request temporary access (WP-Admin and FTP) to your site. Preferably to a test site where the problem has been replicated if possible in order to be of better help and check if some configurations might need to be changed.
I have set the next reply to private which means only you and I have access to it.
I Accessed the toolset registration page from the link within my site and that gave me a DIFFERENT key than logging directly into Toolset and going to my sites page!! WTF! What is the expected process for setting up Toolset sites? Especially addressing setting on the fly testing sites?
