 * Thanks for your report. It looks like you are getting a PHP Notice message when
   you try to use the “Generate Thumbnails” bulk action; is that right? The message
   is harmless, but annoying.
 * I recently found and fixed the cause of this problem, and the current MLA Development
   Version dated 20170605 contains the updated code. You can find more information
   about downloading and installing the Development Version in this earlier topic:
 * [Fatal Error after upgrading to version 2.53](https://wordpress.org/support/topic/fatal-error-after-upgrading-to-version-2-53/#post-9196270)
 * I will be releasing the fix in my next MLA version, but you can use the Development
   Version if you need an immediate result. I will post an update here when the 
   next MLA version goes out. Thanks for your report, your understanding and your
   interest in the plugin.

 * I get this error when I upload files from Media Library [Add New].
    Does not 
   show up when I upload from pages or Woocommerce product pages.

 * Thanks for the additional details; very helpful.
 * Regardless of the source, the fix added to the Development Version should eliminate
   the message. I encourage you to give it a try and let me know if it works for
   you. Thanks!

 * I have released MLA version 2.54, which contains the fix for your “undefined 
   index” issue.
 * I am marking this topic resolved, but please update it if you have any problems
   with the new version. Thanks for your patience and your interest in the plugin.
