   I registered a new user today. For some reason, the same user account was created several times in WordPress. When I delete one of the multiples it deletes all. I try to re-enter it just repeats itself. I am not sure if this is a WordPress database problem, an Alkivia User Community plugin problem (its worked fine forever with no recent updates), or perhaps a cache interference problem (I use hypercache and db cache reloaded). My website is http://www.bmederport.com... check the user community here: http://www.bmedreport.com/bmed-user-community and you will see the name listed 3 times.

   I don't even know where to start with this. Any suggestions? I am not great with database so detail instructions will help. I also use the WP_DB Manager plugin if that is any help.

   Thanks!
   Chris

   start by disabling plugins that affect user registration. kind of a given, since you mention several.

   do whatever you did before. do you get the same result?

   I tested the site by turning on/off these 3 suspect plug-ins:
   1. DB-Cache Reloaded
   2. Hypercache
   3. Alkivia Community

   The bottom line is I could not get my User area to behave appropriately with all 3 turned off. However, the behavior did change which raises some red flags.

   Here is description of the behavior
   1. With all 3 plug-ins off, a newly created user appears in “all” but not in the “author” (the assigned role).

   2. With Alkivia on and DB-Cache on, the user now appears in “all” and twice in “author.”

   3. Nothing changed with Hypercache on/off or uninstalled (but #1 still occurs of course).

   4. The extra listings in “author” do not remove when the user listed in “all” is deleted, though the information in “author” goes blank. It is possible, but I am not sure, that the extra listing may disappear after a certain amount of time(I swear I had several disappear since yesterday, but not entirely sure).

   5. The biggest red flag: I thought maybe the DB-Cache might be influencing this even when deactivated so I try to delete it (both through WordPress and manually). I get this error:

   Warning: require_once(......bmedreport.com/wp-content/plugins/db-cache-reloaded/db-functions.php) [function.require-once]: failed to open stream: No such file or directory in /home/chrisfisher/bmedreport.com/wp-content/db.php on line 700

   My entire site shuts down, and only runs again after I manually reinstall DB-Cache Reloaded. Weird.

   I think I will provide a link to this DB-Cache Reloaded support forum to get them involved, but I still not entirely sure that it is the problem.

   Any suggestions? Is anyone else using these plugin combos?

   Thanks!
   Chris

   @cfisher: as I checked, you use newest DB Cache Reloaded plugin. However, for some reason you still use wp-content/db.php file which was included in version 1.0.x - version 1.1 and up shows nice warning in admin backend instead of this php error. Please try to delete this file manually, and then re-enable this plugin. I have fixed few bugs since version 1.0.x, so please check and let me know if it helped.

   I plan to update my plugin (DB Cache Reloaded) to check if wp-content/db.php file is in sync with plugin version. I will also check this multiple user registration issue.

   Sirzooro,

   Thanks for the quick response. I know for sure now that DB-Cache Reloaded is the problematic plug-in. I deleted the db.php file that you mentioned and this allowed me to successfully delete the entire DB-Cache Reloaded plugin through WordPress (though it still appeared in the root file directory on the backend so I manually deleted it). And my User registration started to work perfectly now!

   Also, I did a fresh re-install of DB-Cache Reloaded through WordPress to see if the misbehavior returned - it did not; however, DB-Cache does not appear to be caching anything now (check the view source of my webpage to verify). Any suggestions?

   Thanks,
   Chris

   Please try to install new version: 1.4. It displays extra informations in case of problems. Let me know if this will help you.

   All problems have been solved with DB-Cache Reloaded 1.4! 1.4 does not interfere with User Registration and even gave me a performance boost! DB-Cache Reloaded now caches about 90% of database queries (previously about 50%). You can verify at my website: http://www.bmedreport.com Nicely done!!
