D7 - How to update a custom theme through upload?

We have a developer that created a custom theme. This was uploaded into our Drupal site using the admin upload theme interface. The developer wishes to update that theme with a new version. I am told that this requires that the old theme is manually deleted. In other words, they cannot upload and install the new version through the admin web interface. Is this correct? If not then what, if anything, must be done to allow such updates to occr?

Articles empty when editing

Hello,

after updating my site from Drupal 7.36 to 7.38 my existing Articels are empty when trying to edit them.
The strange point that there is content in the articels and it shows, but only when clicking edit it is empty.
So I cannot edit anything because it shows empty.

What could be the issue?

Thanks a lot.

Upgrading from Beta11 to Beta12 is not possible

Downloaded Beta 12, as per the documentation (UPGRADE.txt), I removed all except /sites

Copied all Beta12 files, then went to site/drupal/update.php (update.php does not exists, but it seems to try to load).

Then I get the following:

Additional uncaught exception thrown while handling exception.

Fatal error: Allowed memory size while upgrading

Dears,

Kindly I've tried to upgrade drupal to the latest security version, while running Update.php I have following error:
(Fatal error: Allowed memory size of x bytes exhausted (tried to allocate y bytes) in /includes/cache.inc on line 454).

I fix this problem by creating a new file php.ini, and add the code...
php_value memory_limit = "128M"
And add the line
ini_set('memory_limit', '512M');
to my [Drupal 7 root]/sites/default/settings.php file.

But previous fatal error causes: The whole website theme is damaged.

Administrative menu missing

I am a software engineer by training and new to dealing with CMSs including Drupal. I inherited a Web server that I am in the process of moving to the cloud. I have copied all of the Drupal files and database to our new hosted system. Everything looked fine and then I updated the Drupal core and modules that were out of date. 

I went from Drupal 6.26 to 6.36. The good news is that the updates fixed known security issues and now I have a bunch of pretty green checkboxes on the Available Updates page.  The less good news is that the administration menu is gone.
