Home Forums Theme support Shortcode insert button not working Reply To: Shortcode insert button not working

It is my testwebsite and I don’t use a caching plugin. But there is something strange. I activated another theme and after that I tried to activate Inbalance theme again. But I got a 500 error message and couldn’t reach my dashboard or site again. Through ftp I renamed the Inbalance theme and than I got access again so I think the theme itself is the issue. Does the theme work with php 7? Because that is the version I use on the hostingserver.
Do you have a clue what can be triggering this issue?
