I would like to report an issue in WordPress 3.

I was facing the same problem where ‘Screen Options’ menu tab was not visible on the admin dashboard.

I carried out some diagnosis on the PHP code and found that WordPress 3 requires 256Mb of free memory to be available on your web hosting package.

I found two places where this memory limit is being set:
wp-admin/admin.php
wp-admin/includes/file.php

I commented out the code snippets in both of these places and this sorted out the problem.

Because the code was not completely executed, the ‘Screen Options’ tab did not appear, also therefore, there was no ‘Publish’ button visible while adding a new post or a new page.

I would suggest that WordPress Software kindly include a message while installation or upgrade of WP version 3 to notify the administrator that this amount of memory is required to be free on web hosting otherwise there will be issues.

I hope this helps!

Dear all,

For everyone who has faced the problem:
Unable to install new plugins or themes or upgrade to the latest version of word press.

I faced similar problem.

I was not able to install new theme, or upgrade to the latest version. I thought this was linked to me using an older WP version. When I clicked on upgrade to the latest wordpress version, it stopped at: ‘Unpacking the update’.

The problem was:
The file wp-admin/includes/files.php
Modifies the php variable ‘memory_limit’ to 256Mb. This means, you should have 256Mb space available on your web hosting – slightly unrealistic for small space hosting users.

I commented out this piece of code in this PHP file and everything was running back smoothly.

I hope this helps out people!

Cheers.
