and the problem now is that cannot access as an admin ....

Solved now ... added a Menu item with link to www.mysite.com/sign-in

But iam checling that all related to Lenguage / Ajax menu ant the top / Standard Sing In ...is not appearing ot appear with a strange form.

Gaston, does this happen only in your theme?
Try switching to, for example, "Origin" theme and see whether  menus will get back to normal.
You can download "Origin" theme from the Oxwall Store.

Eyyy Aliia .. Thanks!!

As soon as a choose another theme all this things work properly... it seems that the Theme used it is not compatible with the new version of Oxwall ... Shame... Was working hard on it :(

PS: Normally the errors showed up are:

1. Cannot see properly (only in the front) ajax (Online chat, Menu at the top of the page)

2. Cannot see on the main page any sign in area

3. When an user register in my site after confirmation the system send to user almost 360 emails with welcomes.

This is because tried in other themes and work properly all of this...

Opsss! after 30 min. of register an user... the system is sending Welcome emails per 1 - 2 mins.

So i dont know ... please help :D
