Has the site nevertheless updated to 2.5.7?
Is the joomlaupdate component present and working in your Components admin menu?

When you go to Extensions Manager=>Database, is everything OK?

If yes, no worry.

joomlaupdate compnent working? Yes

Hi. I re-installed Joomla with Admin Tools Prof and no error message showed up! Databases looks fine - both sites has the following message though:
Database table structure is up to date.

Use Fix database when an error shows in the database tab.

I'm trying to update 2.5.6 to 2.5.7 through admin control panel's Update Joomla feature using Installation method: Write files directly. All that happens is this message comes up "Updating your Joomla! files. Please wait " and a spinner. Nothing else is going on.

Ideas?
Thanks,
Mark

I have exactly the same problem; update just sits there, spinner turning but nothing is happening...

[infograf768]

In this case, just download the 2.5.6 to 2.5.7 zip pack and install through Extension Manager. Make sure Database is fixed.

[pulp9999]

Well, yes...I did the update manually...but why is this happening or rather not happening?

[infograf768]

No idea. Something to do with the way you may have updated before I guess
