Actually, it is pretty widespread if you read through other issues posted here in the support forum. This issue came up 6 weeks ago when it was considered a conflict with Yoast SEO and is again being reported.
I’ve confirmed that the issue exists even when Analyticator is the ONLY plugin active on the site. It appears to have re-emerged as an issue after a recent WP update?
Can you deactivate all plugins except Analyticator and confirm whether you still see the broken Widget behaviour, Brian?
