Thank you for contacting us.
I am sorry to hear that the Text tab is not accessible while editing and I hope that we can help you get this fixed. Generally something like appears when there are conflicts between your active plugins, and one particular one that we have seen recently is between Easy SEO and Yoast SEO. If you currently have both of those plugins activated, try disabling one to see if that addresses the problem.
