The plugin blocked a backend

Dear @artyus,

Thank you for the topic.

I am really sorry about the issue you are currently experiencing.

We have checked and noticed, that really, there was an issue like this occurring only in the case of multi-sites.

So, thanks a lot for finding out and letting us know about this case/issue.

We will surely fix the issue in the upcoming update of the plugin and will let you know about it.

Thank you.

Dear @artyus,

Thank you for your patience.

We’re excited to announce that a New update of the Secure Copy Content Protection plugin has been released!

We have already fixed the issue in it.

So, please, first of all, make a DB Backup for your safety (you can use Updraft Plus).

Then, update the plugin to the latest version and check again.

Please check this and let us know whether everything works fine or not now.

Thank you.

Hey!

If you are talking about version 2.9.3, then it can activated on multisite, but still don’t work properly.
I found out that this version is incompatible with two plugins:

Wordfence Security
and
External Links — nofollow, noopener & new window

Try looking the cause of the problem here.

Sincerely,
Farid Taziev.
