 * Try:
 * ■flushing any caching plugins you might be running, as well as server and/or 
   browser caches.
    ■deactivating all plugins (yes, all) to see if this resolves
   the problem. If this works, re-activate the plugins one by one until you find
   the problematic plugin(s). If you can’t get into your admin dashboard, try resetting
   the plugins folder by FTP or PhpMyAdmin (read “[How to deactivate all plugins when you can’t log in to wp-admin](http://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F)”
   if you need help). Sometimes, an apparently inactive plugin can still cause problems.
   Also remember to deactivate any plugins in the mu-plugins folder. The easiest
   way is to rename that folder to mu-plugins-old ■switching to the Twenty Twelve
   theme to rule out any theme-specific problems. If you can’t log in to change 
   themes, you can remove the theme folders via FTP so the only one is twentytwelve.
   That will force your site to use it.

 * The problem is with the way that the versions are being read in. Version 1.10.2
   is a lot higher then 1.2.3 – but the system takes those as strings not numbers,
   so it thinks 1.1 vs 1.2 so it will throw a warning like that.
 * As for how to fix, follow what Tara said as thats the right trouble-shooting 
   steps for this sort or problem. When you do find out which plugin/theme is causing
   it, it would be well worth telling the developer on the support page for that
   plugin/theme so that they can get it fixed up.
