 * I’m in: wp-admin/media-new.php
 * The “Bulk Edit” area is open and values ​​have been entered.
 * I press the “Select file” button. Find the desired file and click “Open”.
 * I’m getting this notice and can’t click the “Edit Image” button as usual. The
   progress bar is all blue and says “Processing”.
 * Notice: Undefined variable: mrfh_core in /var/www/html/wp-content/plugins/media-
   library-assistant/includes/class-mla-data.php on line 4730
    54
 * At first glance, it looks like a transposed letter: mrfh instead of mfrh.

 * Thanks for your report, and for your research to find the root cause of the problem.
 * You’re right – it’s a transposed letter defect in the current MLA version.
 * I have uploaded a new MLA Development Version dated 20220330 that corrects the
   defect you reported. You can find step-by-step instructions for using the Development
   Version in this earlier topic:
 * [PHP Warning on media upload with Polylang](https://wordpress.org/support/topic/php-warning-on-media-upload-with-polylang/#post-9625341)
 * Once the Development Version is installed you can try the Add New Media process
   again to confirm the fix. Of course, you could also edit the code you have to
   correct the typo.
 * This fix will be part of my next MLA version, but in the interim it would be 
   great if you could install the Development Version and let me know if it works
   for you. Thanks for alerting me to this MLA defect.

 * I have released MLA version 3.00, which contains the fix required for this topic.
 * I am marking this topic resolved, but please update it if you have any problems
   or further questions regarding the fix. Thanks for alerting me to this MLA defect.
