Thanks for the fix, now I get the same error on a different line.
When going to the settings page:
Fatal error: Cannot use string offset as an array in /home/asha/public_html/ma/wp-content/plugins/manual-image-crop/lib/ManualImageCropSettingsPage.php on line 303
When trying to crop I still get the same error:
Fatal error: Cannot use string offset as an array in /home/asha/public_html/ma/wp-content/plugins/manual-image-crop/lib/ManualImageCropEditorWindow.php on line 53
Any more help would be appreciated.
