 * Hello,
 * I keep getting this message when I try the importer:
 * Tumblr returned an error: 401 oauth_signature [ybT1R5R2zBX6l1CwGpkEpH63zIU=] 
   does not match expected value [ezm27VLTTYSArT13gJjkggkfcN0=]
 * I double checked that I copied the codes correctly; that there were no extra 
   spaces at the beginning or end, etc. but I keep getting the error.
 * Any help would be appreciated!
 * Thank you!

 * I have the same, copied codes correctly etc but I get an error message, but it
   only says ‘Tumblr returned an error:’ and after that there’s an empty space.
 * I read there were some problems with this before but I thought it would be resolved
   with version 0.8.
 * Also curious what the solution to this problem is. Thanks in advance!

 * Hello,
    I am also receiving the error: 401 oauth_signature [oovrNX+wNqRg4GevvapwzaKLwRw
   =] does not match expected value [9+bTQvjIl23FVQuiNlqO2LNBN0g=]
 * I’ve also checked everything to make sure it matched correctly. If anyone has
   a resolution it would be greatly appreciated.

 * Hi,
 * I am also receiving the error: 401 oauth_signature [e+FN4i87Is14SkJOP7hcwpRCjYk
   =] does not match expected value [2ZP8CfXHaj61SAInJTiwDA+cFX0=]
 * I also triple checked all of the Oauth values. If anyone has a solution to this
   problem, please let us know. It seems others are having this problem as well.
 * Thanks

 * If you change your password, then the codes will become invalid. Also, authorizations
   only last a limited time, they will expire eventually. There are a few other 
   things you can do to cause this as well.
 * To fix it, basically just use the clear-all-data button and start over with the
   auth process again to get new codes into the plugin.
 * Note that the Tumblr Importer is meant for migration, not continuous usage. It’s
   expected that you’ll import the data into WordPress, then start using WordPress.
   It won’t work over a long period of time, it’s generally a one-time-import that
   the plugin is designed for here.
