Thanks for your report and for including the name of the column you are sorting on; very helpful. The MLA defect you discovered only affects sorting on columns where the column identifier does not match the name of the corresponding database column.
I have uploaded a new MLA Development Version dated 20181206 that corrects the problem. To get the Development Version you can follow the instructions in this earlier topic:
PHP Warning on media upload with Polylang
It would be great if you can install the Development Version and let me know how it works for you. Thanks for your help in testing the fix.
Fantastic! It seems to work, at least for the date column.
It’s a brilliant plugin you’ve made. Congratulations! I’ve managed to clean up the media archives on a bunch of sites in no time, removing orphans and adding missing alt texts, etc.
The way you can use template bits for fields in a bulk edit is genius. That way you can copy fields around in many interesting ways.
Thanks again.
Thanks for confirming the fix and for the positive feedback. MLA can be complex but has developed into a power tool based on features I’ve added in response to support topics over the years.
Thanks as well for posting a good review. Reviews and positive feedback are great motivators for working on the plugin and supporting its users.
I have released MLA version 2.76, which contains the fix for the issue you identified.
I am marking this topic resolved, but please update it if you have any problems or further questions regarding the new version. Thanks again for your help with this issue.
