Some users are reporting bX-l4u1mh when editing the Layout of their blog. We're investigating the issue and will report back as soon as we have more information.

Update, 12/15: This is now fixed. Thanks for your patience.

"Layout" rearranging for users with customized templates is currently broken. We are investigating the issue.

Some Blogger in draft users are not seeing any gadgets listed under the "Featured Gadgets" tab when attempting to add new gadgets to their layouts.

The vertical scrollbar for the page elements editor is currently missing. Thus, users with a large number of page elements won't be able to access them all.

Update, 3/15: This has been fixed.

Line breaks within the <b:skin> tag are removed when viewing a blog's page source.

Update, 2/25: This has been fixed.

Since 2/12, the Layouts page elements editor has not had scrollbars around the wireframe template. Until this is resolved, you can often scroll wide templates by clicking and dragging on empty space.

Nevertheless, we encourage template designers to use the body#layout CSS selector to add CSS styles that adapt templates to the editor.

Update, 2/29: The Layouts editor now expands to the size of the template.

The shrink-to-fit feature for headers and images only affects newly-uploaded images. To workaround this issue, simply upload your image again.

Update, 2/29: The “shrink to fit” checkbox now only appears before uploading an image.

The preview of your blog on the “Fonts and Colors” page may incorrectly show your posts and sidebar in the same column.

Archives page elements set to “Hierarchy” are not showing posts for any months beyond the first three.

Update, 12/19: This has been fixed.

JavaScriptInTemplate734670

Some script tags inserted manually into the template code, instead of inserted through a HTML/JavaScript page element, will prevent the Template Page Elements tab from fully loading. For instance, some users report that they are unable to view the "Add Page Element" link. To workaround this issue, please ensure that all JavaScript is inserted via a page element.

RectangularPhotoDisplay

Some rectangular images uploaded via the Picture widget in Layouts are being displayed as square, and are thus distorted.

AdSenseWidgetError

Adding or editing an AdSense page element from your Layouts section may return the error message "An internal error occurred. Please try again." As a workaround to this issue, copy your AdSense code from your AdSense account and insert it into an HTML/JavaScript page element in the layouts section of your blog.

CantSeeAddPageElement

Some users report that they are unable to see the “Add Page Element” links in their Template | Page Elements tab. This occurs when the blog incorrectly tries to display from a URL with “www2” instead of “www.” To work around this problem, simply remove the “2” from the URL.

Update, 5/24: If you are still experiencing this issue but do not have a "2" in your URL, then there may be JavaScript causing the "Add Page Element" links to disappear. Please ensure that you put all JavaScript into JavaScript page elements, instead of directly into your template code.

LayoutsInSafari

Drag-and-drop customization of the new Blogger’s new template system (layouts) does not work in Safari, nor does fonts and colors customization. You must use either Firefox or Internet Explorer 6+ to use these features of the new Blogger. (They also work mostly with Opera 9, though with some visual glitches.)

FTPNoLayoutsFeature

The new drag-and-drop template feature, Layouts, is not available for blogs published via FTP. Update, 12/18: Because Layouts relies heavily on new Blogger’s dynamic serving of pages, this is unlikely to be supported soon if ever.
