Hello. Thank you for contacting the Toolset support.
That is really strange. Can you please check your browser's console and check if you able to locate any possible javascript error?
If there is no JS error, I need to take a look at your install.
*** 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.
Yes - indeed. I can see the issue with the site you shared and at the same time I can see the following JS error on the broswer's console and that is coming from Types plugin and if forms or layout plugin is active, the error is coming from the that plugin.
What if you try to reinstall all the plguins - does that help? If no:
- What if you try to install the English version of WordPress and check if you see the same issue.
