Widgets in sidebar not showing under design/widgets in dashboard of wc2 2.5

[Ainsaree]

I have widgetize anything as a plugin. Under Design/Widgets you can list what widgets are available, and which are being used and where. As my widgets are shown in each sidebar (1 and 2). Selection sidebar 1 displays all the widgets correctly that are being used, but selecting sidebar 2 in the same drop down box displays the following error : %BEG_OF_TITLE%Calendar%END_OF_TITLE%

screenshot of error

sidebar 1 - works without error

You sure this isn't just the widget's fault? Does it happen with the plugin disabled?

Nope, the calendar widget is very broken, and here's a fix for that particular widget:

​http://trac.wordpress.org/ticket/6500#comment:2

but that merely fixes the symptom, not the cause.

Milestone 2.5.2 deleted

worksforme in 2.7

Re-open with steps if still reproducable.

Still happens...

Add the WP-Calendar to Kubrick's sidebar. Click save.

I'm still not seeing it (against trunk) in either Linux or IIS based sites.

What sort of hosting is it failing in? Mine are php 5 based does it fail in php 4?

I've nailed down steps to reproduce:

• create a new 2.7 install
• delete the initial post
• insert the calendar widget

Attached patch is against my local SVN, but it should work fine. It:

• Fixes the issue by moving the call to ob_start() to after the check
• Sets the cache when no posts are present
• Optimizes the query that checks if posts are present

(In [10708]) Fix calendar widget when there are no posts. Optimize query. Props Denis-de-Bernardy. fixes #6442
