unable to edit theme php files after activating plugin

Yes this is the free version. If it's fixed with the paid version I will purchase it.

Hello

Are you using the free version?
Could you send us the access of your website to take a look?

Hey,

When I activate the plugin I'm not able to make any more changes in the php files of my theme.
I will get this message.
Unable to communicate back with site to check for fatal errors, so the PHP change was reverted. You will need to upload your PHP file change by some other means, such as by using SFTP
When I disable the plugin I'm able to edit those files without any problem.

Best regards,
RG
