This can be due to a conflicting plugin, might be worth deactivating things and trying again in case that’s the problem.

Nice,

I have found the plugin in conflict: Restricted Site Access

I need to restrict site only user logged.

Good stuff, thanks for the update.

the problem is that if the active plugin that I can not use the forum...

there is a solution ?

Sorry, is this not just affecting the installation process? It normally happens because a conflicting plugin interferes with the ajax/json response of the process. It should just be a case of deactivating the offending plugin, installing/updating, then you should be up and running and able to reactivate the plugin that was causing the problem.

Unfortunately not in my case.

As once reactivated , for example, if I make a new group simple:press go in loop , instead locking it works.

Then that does, I am afraid, suggest a scripting conflict. If you know how to use the web script console you may be able to track down the culprit.

Desperate times call for desperate measures!

I have installed other plugin:

https://wordpress.org/plugins/site-secrets/

this is compatible 😉

Best regards

okay, cool…
