I have followed these instructions, but I'm still getting the error - Site key not matching in 'communication error details'. (I moved the site from a dev.sitename.co.uk to just sitename.co.uk)
Toolset doesn't have an Updates in its Dashboard. But I went back to the Plugins page, and all seems to be fine now, so as I first thought there is a delay after recreating the key and entering it in WordPress plugins.
JFYI I had previously gone to Plugins, clicked Registered under Toolset Blocks and clicked Check for updates and that was fine, green tick remained etc.
But either way it seems to have resolved under it's own volition.
Can you please share admin access details and let me check whats going wrong with your setup.
*** Please make a FULL BACKUP of your database and website.***
I would also eventually need to request temporary access (WP-Admin) 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'm not sure it's worth spending time on it as it's all resolved now, i.e. when I click on Plugins in WP Admin, I don't see the error message. Unless you think there is a fundamental issue? Let me know.
