 * Hi everyone,
    as a lot of other person, I had several problems after upgrading
   to 2.3.2, but all the fixing did not worked for me. I write my experience here
   to help Hector fixing his great plugin.
 * My site was never down because of the plugin as reported by someone. After upgrading
   I got the database error as many others, and tried deactivation and reactivation
   the plugin several times, but it’s still not working in several ways:
 * – I can’t see no thumbnail, even if the cache folder is writable.
 * – The update destroyed all my previous stats. There was no data during a couple
   of days until I manually cleared the table. Now it’s recording the visit again,
   but all the old data are gone.
 * – when I activate the plugin I get one of these two errors (I’m sorry, I can’t
   say what trigger one, or the other):
    `The plugin generated 504 characters of
   unexpected output during activation. If you notice “headers already sent” messages,
   problems with syndication feeds or other issues, try deactivating or removing
   this plugin.` Or `WordPress database error: [Duplicate entry 'ngg_db_version'
   for key 2] ALTER TABLE wpfabiano_options ADD UNIQUE KEY option_name (option_name)
   WordPress database error: [Duplicate key name 'type_status_date'] ALTER TABLE
   wpfabiano_posts ADD KEY type_status_date (post_type,post_status,post_date,ID)
 * As a consequence, i switched back to 2.2.1 that is working just fine. I loosed
   all the stats but I don’t really mind.
 * Hope this will help. Good luck with the fixing Hector!
    cheers Fab

 * Hi Fab,
 * > WordPress database error: [Duplicate entry ‘ngg_db_version’ for key 2]
   >  ALTER
   > TABLE wpfabiano_options ADD UNIQUE KEY option_name (option_name) WordPress 
   > database error: [Duplicate key name ‘type_status_date’] ALTER TABLE wpfabiano_posts
   > ADD KEY type_status_date (post_type,post_status,post_date,ID)
 * This one has nothing to do with my plugin. It must be another plugin causing 
   this conflict – see `wpfabiano_options` and `ngg_db_version`.
 * My suggestion: try deactivating all your plugins, and re-enable them one by one
   to see what is causing this.

 * Hola Hector,
    thx for yur kind answer. yes I know the table is from another plugin,
   actually the very popular next gen gallery. But wp popular post 2.2.1 lived smoothly
   with nextgen during several months, and it’s the activation of popular post 2.3.2
   that trigger the error. i don’t know why. Anyway, I’m happy with 2.2.1. Can’t
   say way, but it seems 2.3.2 has a lot of problems, so I’ll wait for a new stable
   version. Again thank you very much for your great work cheers Fab

 * I’ll try installing that plugin and see if I can replicate your issue. However,
   it won’t be anytime soon as I’m a bit short of time now.
