Hi I have the same issue but I use WPMU does anybody know if i deactivate and delete Contact form 7 from the network will it delete all the forms on the sites?
Example some plugins can be deleted and reinstalled and they pick up where they left off but because Contact form 7 uses short codes i am not sure if it will work in the same way.
Same issue for me i have uninstalled for now using file manager and The Network Admin page is back online.
I will reinstall and try the fix in the first post.
