Array and string offset access syntax with curly braces is deprecated

Thanks for your report. I had a look at the source code for MLA v2.81 and found a possible match to this message, but on line 3994, not 3985. Can you confirm the MLA version you are using? The problem is harmless, except for the message.

I will correct the problem I found and release a new Development Version shortly. The fix will also be in the next MLA version I release, but that won’t be until the end of February. I will post an update here when the Development Version goes out.

Thanks for alerting me to this MLA issue!

Thanks for confirming the details of your version and messages. I have corrected both of the curly brace occurrences you reported.

I have uploaded a new MLA Development Version dated 20200210 that includes the corrected code. You can find step-by-step instructions for using the Development Version in this earlier topic:

PHP Warning on media upload with Polylang

It would be great if you can install and test the Development Version, then let me know how it works for your application. Thanks for motivating this MLA fix.
