Working on Drupal 7.67 with Views Bulk Operations 7.x-3.5
Trying to modify entity values just like a few days ago successfully and today the site crashed
mod_fcgid: stderr: PHP Fatal error: Cannot unset string offsets in /home/my_site/public_html/modules/field/field.default.inc on line 41
VBO is used on an admin Views, built to manage content per batch.
I have tried the @Kenorb tool about var_dump in field.default.inc (in the related question above) and it led to a specific field (List text) for which I added a default value but still the VBO action failed. I have tried to modify this specific field through VBO action and unfortunately it failed again.
Is there any recent module update that could have changed something here? Chaos tools? Entity API?
Any tip here would be much appreciated.
