I got this

I got this from siteground - can you confirm the plugins are good for PHP 7 - many thanks

I investigated your case and found tha the issue is caused by the following plugins for your WordPress application:

Code:
wpmu-dev-seo

wpmudev-updates

After I temporarily disabled them the check finished almost immediately as you can see from the screenshot:

This means that the plugins are preventing the the check from finishing, so I cannot say for sure that your website will function properly with them and PHP version 7 enabled. However that does not mean that the will not work at all. You can change the PHP version through your cPanel => PHP Version Manager and switch it back to 5.6 if your website does not function properly:

Please let us know if you need any further assistance.
