Not sure where to post this or if it benefits anybody...
I have Gravity Forms installed in WordPress and spent an hour trying to figure out why my WP Updates is showing "1 Plugin Update" when there's no update available. I started investigating, came across this DB fix, and end up deactivating plugins until I came across Gravity Forms. Under GF Updates, the result came back with "Your version of Gravity Forms is up to date.", so I started deactivating/reactivating add-ons and finally found the culprit, Paypal Add-On.
An update was available for Paypal Add-On but there was no notice telling me that this add-on requires updating. Anyways, I re-downloaded the Paypal Add-On from this forum, replaced my old one and everything is working fine now.
Thought I'd share the experience. Please let me know if there's a setting that I missed to warn me or a place where I'm supposed to check for any Add-On updates. Cheers!
