Did you move your wordpress page to different server/database and now you are unable to login to wordpress admin interface, because you receive “You do not have sufficient rights to access this page“? Did you change table_prefix in wp-config.php file? The solution is simple – check user usermeta (meta_key) and options (option_name) tables. There are some keys that use table_prefix
If you are using rather exotic Windows regional settings you might get the following error: Locale not recognized The solution is simple as mentioned here. Just set the JAVA_TOOL_OPTIONS environment variable to this: -Dfile.encoding=UTF8 -Duser.language=en -Duser.region=US -Duser.country=US JDBC won’t use regional setting to determine locale to be used (and probably unsupported at the moment) anymore .
