I'm using an offline WordPress development tool called hidden link with the default WordPress theme and the latest version of Toolset Types (Version 3.0.8).
While using it and activating the types plugin it causes the WordPress admin area to have a white screen, with no way of accessing the WordPress admin unless you disable the plugin manually by renaming it in the WordPress plugins folder.
This does not happen with any of the other plugins, and even if you deactivate all other WordPress plugins and just leave Toolset Types active, it still causes the white screen.
It looks like that the simplexml_load_file function is not available, which may be because on your server it does not include the SimpleXML module and allow_url_fopen turned on with your php.ini file
Please contact your server/hosting authority and ask them to activate the SimpleXML module on your server and try to resolve your issue.
