Error causing site unavailable with latest Showcase and Widget Framework

[Mouth]

I have Showcase 1.3.1 and installed latest Widget Framework 2.4.6d, on XF 1.2.3 for my DEV site. After upgrading WidgetFramework, I now get the following error across the whole site ...

An exception occurred: Undefined index: attachments in XF/library/NFLJ/Showcase/WidgetRenderer/TabbedItems.php on line 64

It appears if I do a browser forced refresh (CTRL|CMD - R), then it will sometimes work.

Its a cache issue with the block. I THINK you can disable the block and re enable it to create a new cache for it (worth a shot). Its happen to me a few times when I upgrade to new versions.

Thanks. Tried that, but hasn't worked for me. Even tried disabling WidgetFramework add-on entirely, loading site pages, then re-enabling WidgetFramework again, and then enabling the Showcase block. Unfortunately, still get the error.
I've disabled the block for now.

ok, I just upgraded to [bd] Widget Framework 2.4.6d. Im not running any sever cache, so that could also be an issue. The error is with one of the OPTIONS (which the framework caches). Can you EDIT the Block and check and uncheck the 'Display Thumbnail' option?

 

[Mouth]

That appears to have fixed it. I had that option un-ticked (not showing thumbnails for my widget), so ticked it and refreshed a few site pages, then un-ticked it again.
Not getting the error anymore.
Thanks Bob!

oh good! Please keep an eye on it to see if it happens again.
