In a site using Wordpress 3.8 and Atahualpa 3.7.13, I'm encountering the same problem as described in previous forum thread: http://forum.bytesforall.com/showthread.php?t=20598.

Sidebar Login Plugin does not display the Logged-in User Avatar unless you refresh the page. Same on any page you had open in your Browser's cache before logging in. But, if you navigate to a new page after logging in, then the logged-in User Avatar displays.

In addition, with the Member Access plugin activated, if you login from a "Members only" restricted access page, the "Members Only" restricted access message continues to display, and it does not recognize you as logged in for any of the Members Only pages. (You continue to go only to the Members Access re-direct page with the "Sorry, Members Only" message.)

After trying to log in from a Members Only page, if you then log out and log back in from a public page, you are still denied access to all the Members Only pages. Only when you log out, clear the browser's cache, and then log back in from a public page (and refresh the page to display the logged-in user avatar), are you then permitted access to the Members Only pages.

Have tried de-activating other plugins, but no help.

Any help will be much appreciated!

What happens if you switch to twenty twelve?
Do you have a caching plugin active?

No caching plugin installed or active.

I do not have this problem with the exact same set of plugins and same content files using Wordpress 3.2.1 and Atahualpa 3.6.4. The problem arose only when I moved the site to another host, and in the process had to update to Wordpress 3.8 and Atahualpa 3.7.13, and update all the plugins.

The active plugins on the site include: Akismet, Comment Reply Notification, Email Alerts, List Category Posts, Login Logo Customization (by Pigi), Login Page Logo Link Changer (for logo on wp-admin sign in page), Mail From, Member Access, Nextgen Gallery, Post Page Associator, Query Posts, Show ID for Post/Page/Category/Tag/Comment, Subpage Navigation Widget, Tako Movable Comments, User Profile Message (adds a message to the backend profile page), User Role Editor, and Widget Logic.

All are latest versions.

What happens if you switch to twenty twelve?

Tried Twenty Twelve. Can't test, because site (which is designed for Atahualpa) does not render properly in Twenty Twelve -- Sidebar login widget does not appear, member only pages are showing in menu and member only content showing in sidebars throughout, etc.

Also tested with Atahualpa 3.6.4 (the original version of Atahualpa used for this site, which worked with Wordpress 3.2.1). But, same problem occurs in the new site with Wordpress 3.8

Basically, in summary, there seem to be two problems:

1. The Sidebar Login widget does not show you as logged in on the page on which you log in - or on any other pages open in your browser's cache at the time of login - until you refresh the browser; and

2. If you have any Members Only pages open in your brower's cache (i.e. redirected to the "Members Only" message page) at the time of login, then the Members Only plugin permanently redirects you to the "Members Only" message page for those pages, even after you login -- but allows you access after login to any Members Only pages that were not open in your browser's cache at the time of login.

These problems are occurring across all browsers and on several computers.

Help!

1. The Sidebar Login widget: did you try the solutions in http://wordpress.org/support/topic/p...gin?replies=15 ? this looks like a plugin issue

2. Members Only plugin: have you contacted the plugin author? I note that the plugin hasn't beenupdated in over 2 years, it may be broken with th ecurrent version of WP.
