 * I’m trying to access my admin panel, but when I log in I get the following error
 * Fatal error: Call to undefined function pib_render_button() in /home/queenofs/
   domains/melissamiksch.com/wp-content/plugins/pinterest-pin-it-button/class-pinterest-
   pin-it-button.php on line 137
 * My website is working fine from a user standpoint, but I can’t get in to the 
   back end to edit anything. I’m fairly certain this is an issue with my pinterest
   plugin…. but I can’t deactivate it if I can’t get in.
 * Here’s what I’ve tried: manual update of 4.2.1 via FTP. Using both Chrome and
   IE9.
 * website is [http://www.melissamiksch.com](http://www.melissamiksch.com)

   to rename or remove the folder `/wp-content/plugins/pinterest-pin-it-button/`–
 * then re-upload the plugin

 * Hey mdmiksch,
 * Sounds like you will need to rename `/wp-content/plugins/pinterest-pin-it-button`
   to `/wp-content/plugins/pinterest-pin-it-button.HOLD`. Change that plugin directory
   name via FTP and I bet you’ll be able to login to your Dashboard again.

 * Thanks!! Totally worked – I just wasn’t sure where to go, and I’m terrified of
   breaking my site. 🙂
