I have had a Wordpress.com hosted site running for 10+ years without any plugins or problems until a few days ago when I installed my first plugin, wpDiscuz plus 4 of your addons: User Notifications, Advanced Likers, Comment Search, and Embeds.
I do not know if the problems I am seeing are caused by changes WordPress made to support plugins, or by some problem with wpDiscuz. I do not think the problems were caused by your addons because I saw the problems before I purchased and installed the 4 addons.
Symptoms:
- logged in users lost black bar at top of page with WordPress notification
- users reported problems logging in with broken connection between WordPress and Jetpack (as admin I did not see this problem)
- I see a new version of users with same name/email in the comments admin page after they posted a comment: one user with # comments after plugin install and one user with # comments before plugin install
- logged in users display as Guest on their Likes
- logged in users display correct name on their comments
A user discovered they could fix the WordPress/Jetpack login problem by clearing their browser cache after which:
- the WordPress notification bar returned
- new likes now correctly display the user’s name
- old likes still incorrectly display Guest
In the comment admin page I now see 3 versions of users with the same name/email:
- one with # comments before plugin install
- one with # comments after plugin install
- one with # comments after clearing browser cache to fix link between WordPress and Jetpack
Please advise how I can:
- fix WordPress/Jetpack login problem without requiring all users to clear their browser cache
- merge multiple instances of users back into one instance with correct total comments
- fix the likes that are incorrectly identified as Guest
I do not know if this is a WordPress problem or a wpDiscuz problem. Let me know if you think I should be speaking with WordPress support.
Thanks for your help.
